The OPA2652 is a dual, low-cost, wideband voltage
feedback amplifier intended for price-sensitive
applications. It features a high gain bandwidth
product of 200MHz on only 5.5mA/channel quiescent
current. Intended for operation on ±5V supplies, it
also supports applications on a single supply from
+6V to +12V with 140mA output current. Its classical
differential input, voltage-feedback design allows
wide application in active filters, integrators,
transimpedance amplifiers, and differential receivers.
HIGH SLEW RATE: 335V/µsec
SUPPLY VOLTAGE: ±3V to ±6V
The OPA2652 is internally compensated for unity
gain stability. It has exceptional bandwidth (700MHz)
as a unity gain buffer, with little peaking (0dB typ).
Excellent DC accuracy is achieved with a low 1.5mV
input offset voltage and 300nA input offset current.

This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.
ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be
more susceptible to damage because very small parametric changes could cause the device not to meet its published
specifications.

APPLICATIONS INFORMATION
Wideband Voltage Feedback Operation
Voltage swings reported in the specifications are
taken directly at the input and output pins, while
output powers (dBm) are at the matched 50Ω load.
For the circuit of Figure 28, the total effective load
will be 100Ω || 804Ω. Two optional components are
included in Figure 28.
The OPA2652 is a dual, low-power, wideband
voltage feedback operational amplifier. Each channel
is internally compensated to provide unity gain
stability. The OPA2652 voltage feedback architecture
features true differential and fully symmetrical inputs.
This architecture minimizes offset errors, making the
OPA2652 well-suited for implementing filter and
An additional resistor (174Ω) is included in series
with the noninverting input. Combined with the 25Ω
DC source resistance looking back towards the
signal generator, this additional resistor gives an
input bias current cancelling resistance that matches
the 201Ω source resistance seen at the inverting
input (see the DC Accuracy and Offset Control
section). In addition to the usual power-supply
decoupling capacitors to ground, a 0.1µF capacitor is
included between the two power-supply pins. In
practical printed circuit board (PCB) layouts, this
optional-added capacitor typically improves the
2nd-harmonic distortion performance by 3dB to 6dB.
instrumentation designs. As
a dual operational
amplifier, OPA2652 is an ideal choice for designs
that require multiple channels where reduction of
board space, power dissipation and cost are critical.
Its AC performance is optimized to provide a gain
bandwidth product of 200MHz and a fast rise time of
2.0ns, which is an important consideration in
high-speed data conversion applications. The low
DC input offset of ±1.5mV and drift of ±5µV/°C
support high accuracy requirements. In applications
requiring a higher slew rate and wider bandwidth,
such as video and high bit rate digital
communications, consider the dual current feedback
OPA2694, or the OPA2691.
Figure 29 shows the DC-coupled, gain of –1, bipolar
supply circuit configuration that is the basis of the
specifications and typical characteristics at G = –1.
The input impedance matching resistor (57.6Ω) used
for testing gives a 50Ω input load. A resistor (205Ω)
connects the noninverting input to ground. This
configuration provides the DC source resistance
matching to cancel outputs errors arising from input
bias current.
Figure 28 shows the DC-coupled, gain of +2, dual
power-supply circuit configuration used as the basis
of the ±5V specifications and typical characteristics.
This configuration is for one channel. The other
channel is connected similarly. For test purposes, the
input impedance is set to 50Ω with a resistor to
ground and the output impedance is set to 50Ω with
a series output resistor.

Computer simulation of circuit performance using
SPICE is often useful when analyzing the
performance of analog circuits and systems. This
method is particularly true for video and RF amplifier
circuits where parasitic capacitance and inductance
can have a major effect on circuit performance.
Check the Texas Instruments web site (www.ti.com)
for available SPICE products (note that not all parts
have models). These models do a good job of
predicting small-signal AC and transient performance
under a wide variety of operating conditions. They do
not do as well in predicting the harmonic distortion or
dG/dφ characteristics. These models do not attempt
to distinguish between the package types in
small-signal AC performance.

OPERATING SUGGESTIONS
Optimizing Resistor Values
causes the phase margin to approach 90° and the
bandwidth to more closely approach the predicted
value of (GBP/NG). At a gain of +5, the 45MHz
bandwidth shown in the Electrical Characteristics is
close to that predicted using this simple formula.
Because the OPA2652 is a unity gain stable voltage
feedback op amp, a wide range of resistor values
may be used for the feedback and gain setting
resistors. The primary limits on these values are set
by dynamic range (noise and distortion) and parasitic
capacitance considerations. For a noninverting unity
gain follower application, the feedback connection
should be made with a 25Ω resistor, not a direct
short. This configuration isolates the inverting input
capacitance from the output pin and improves the
frequency response flatness. Usually, the feedback
resistor value should be between 200Ω and 1.5kΩ.
Below 200Ω, the feedback network presents
additional output loading that can degrade the
harmonic distortion performance of the OPA2652.
Above 1.5kΩ, the typical parasitic capacitance
(approximately 0.2pF) across the feedback resistor
may cause unintentional bandlimiting in the amplifier
response.
Inverting Amplifier Operation
Because the OPA2652 is
a
general-purpose,
wideband voltage feedback op amp, all of the
familiar op amp application circuits are available to
the designer. Inverting operation is one of the more
common
requirements
and
offers
several
performance benefits. Figure 29 shows a typical
inverting configuration.
In the inverting configuration, three key design
consideration must be noted. First, the gain resistor
(RG) becomes part of the signal channel input
impedance. If input impedance matching is desired
(which is beneficial whenever the signal is coupled
through a cable, twisted pair, long PCB trace or other
transmission line conductor), RG may be set equal to
the required termination value and RF adjusted to
give the desired gain. This approach is the simplest,
and results in optimum bandwidth and noise
performance. However, at low inverting gains, the
resulting feedback resistor value can present a
significant load to the amplifier output. For an
inverting gain of –1, setting RG to 50Ω for input
matching eliminates the need for RM but requires a
50W feedback resistor. This configuration has the
interesting advantage that the noise gain becomes
equal to 2 for a 50Ω source impedance—the same
as the noninverting circuits considered above.
However, the amplifier output now sees the 50Ω
feedback resistor in parallel with the external load. In
general, the feedback resistor should be limited to
the 200Ω to 1.5kΩ range. In this case, it is preferable
to increase both the RF and RG values as shown in
Figure 29, and then achieve the input matching
impedance with a third resistor (RM) to ground. The
total input impedance becomes the parallel
combination of RG and RM.
A good rule of thumb is to target the parallel
combination of RF and RG (see Figure 28) to be less
than approximately 300Ω. The combined impedance
RF || RG interacts with the inverting input
capacitance, placing an additional pole in the
feedback network, and thus a zero in the forward
response. Assuming a 2pF total parasitic on the
inverting node, holding RF || RG < 300Ω keeps this
pole above 250MHz. By itself, this constraint implies
that the feedback resistor RF can increase to several
kΩ at high gains. This increase is acceptable as long
as the pole formed by RF and any parasitic
capacitance appearing in parallel is kept out of the
frequency range of interest.
Bandwidth vs Gain: Noninverting Operation
Voltage feedback op amps exhibit decreasing
closed-loop bandwidth as the signal gain is
increased. In theory, this relationship is described by
the Gain Bandwidth Product (GBP) shown in the
specifications. Ideally, dividing GBP by the
noninverting signal gain (also called the Noise Gain,
or NG) predicts the closed-loop bandwidth. In
practice, this prediction only holds true when the
phase margin approaches 90°, as it does in high
gain configurations. At low gains (increased
feedback factor), most amplifiers exhibit a wider
bandwidth and lower phase margin. The OPA2652 is
The second major consideration, touched on in the
previous paragraph, is that the signal source
impedance becomes part of the noise gain equation
and influences the bandwidth. For the example in
Figure 29, the RM value combines in parallel with the
external 50Ω source impedance, yielding an effective
driving impedance of 50Ω || 57.6Ω = 26.8Ω. This
impedance is added in series with RG for calculating
the noise gain (NG). The resulting NG is 1.94 for
Figure 29 (an ideal source would cause NG = 2.00).

(see Figure 28). This
configuration results in a typical gain of +1 bandwidth
of 700MHz, far exceeding that predicted by dividing
the 200MHz GBP by NG = 1. Increasing the gain
The third important consideration in inverting
amplifier design is setting the bias current
cancellation resistor on the noninverting input (RB). If
this resistor is set equal to the total DC resistance

error, as a result of the input bias currents, is
reduced to (Input Offset Current) • RF. If the 50Ω
source impedance is DC-coupled in Figure 29, the
total resistance to ground on the inverting input will
be 429Ω. Combining this in parallel with the
feedback resistor gives 208Ω, which is close to the
RB = 205Ω used in Figure 29. To reduce the
additional high-frequency noise introduced by this
resistor, it is sometimes bypassed with a capacitor.
As long as RB <300Ω, the capacitor is not required
since its total noise contribution is much less than
that of the op amp input noise voltage.
directly on the output pin. When the amplifier
open-loop output resistance is considered, this
capacitive load introduces an additional pole in the
signal path that can decrease the phase margin.
Several external solutions to this problem have been
suggested. When the primary considerations are
frequency response flatness, pulse response fidelity,
and/or distortion, the simplest and most effective
solution is to isolate the capacitive load from the
feedback loop by inserting a series isolation resistor
between the amplifier output and the capacitive load.
This resistor does not eliminate the pole from the
loop response, but rather shifts it and adds a zero at
a higher frequency. The additional zero acts to
cancel the phase lag from the capacitive load pole,
thus increasing the phase margin and improving
stability.
Output Current and Voltage
The OPA2652 specifications in the spec table,
though familiar in the industry, consider voltage and
current limits separately. In many applications, it is
the voltage • current, or VI product, that is more
relevant to circuit operation. Refer to the Output
Voltage and Current Limitations plot in the Typical
Characteristics. The X and Y axes of this graph show
the zero-voltage output current limit and the zero
current output voltage limit, respectively. The four
quadrants give a more detailed view of the device
output drive capabilities, noting that the graph is
bounded by a Safe Operating Area of 1W maximum
internal power dissipation (500mW for each
channel). Superimposing resistor load lines onto the
plot shows that the OPA2652 can drive ±2.2V into
50Ω or ±2.5V into 100Ω without exceeding the output
capabilities, or the 1W dissipation boundary line.
The Typical Characteristics show the recommended
RS versus capacitive load and the resulting
frequency response at the load. Parasitic capacitive
loads greater than 2pF can begin to degrade the
performance of the OPA2652. Long PCB traces,
unmatched cables, and connections to multiple
devices can easily exceed this value. Always
consider this effect carefully, and add the
recommended series resistor as close as possible to
the OPA2652 output pin (see Board Layout
Guidelines).
Distortion Performance
The OPA2652 provides good distortion performance
into a 100Ω load on ±5V supplies. Increasing the
load impedance improves distortion directly.
Remember that the total load includes the feedback
To maintain maximum output stage linearity, no
output short-circuit protection is provided. This
configuration will not normally be a problem since
most applications include a series matching resistor
at the output that limits the internal power dissipation
if the output side of this resistor is shorted to ground.
However, shorting the output pin directly to the
adjacent positive power supply pin will, in most
cases, destroy the amplifier. Including a small series
resistor (5Ω) in the power-supply line will protect
against this. Always place the 0.1µF decoupling
capacitor directly on the supply pins.

(Figure 28), this is sum of RF + RG, while in the
inverting configuration, it is only RF. Also, providing
an additional supply decoupling capacitor (0.1µF)
between the supply pins (for bipolar operation)
improves the 2nd-order distortion slightly (3dB to
6dB).
It is also true that increasing the output voltage swing
increases harmonic distortion.

A fine scale output offset null, or DC operating point
adjustment, is often required. Numerous techniques
are available for introducing DC offset control into an
op amp circuit. Most of these techniques add a DC
current through the feedback resistor. In selecting an
offset trim method, one key consideration is the
impact on the desired signal path frequency
response. If the signal path is intended to be
noninverting, the offset control is best applied as an
inverting summing signal to avoid interaction with the
signal source. If the signal path is intended to be
inverting, applying the offset control to the
noninverting input may be considered. However, the
DC offset voltage on the summing junction sets up a
DC current back into the source which must be
considered. Applying an offset adjustment to the
inverting op amp input can change the noise gain
and frequency response flatness. For a DC-coupled
inverting amplifier, Figure 36 shows one example of
an offset adjustment technique that has minimal
impact on the signal frequency response. In this
case, the DC offset current is brought into the
inverting input node through resistor values that are
much larger than the signal path resistors. This
configuration ensures that the adjustment circuit has
minimal effect on the loop gain, and therefore on the
frequency response as well.

Evaluating these two equations for the OPA2652
circuit and component values shown in Figure 28
gives a total output spot noise voltage of 17nV/√Hz
and a total equivalent input spot noise voltage of
8.4nV/√Hz. This noise includes the noise added by
the bias current cancellation resistor (205Ω) on the
noninverting input. This total input-referred spot
noise voltage is only slightly higher than the 8nV/√Hz
specification for the op amp voltage noise alone.
This result will be the case as long as the
impedances appearing at each op amp input are
limited to the previously recommend maximum value
of 300Ω. Keeping both (RF || RG) and the
noninverting input source impedance less than 300Ω
satisfies both noise and frequency response flatness
considerations. Since the resistor-induced noise is
relatively negligible, additional capacitive decoupling
across the bias current cancellation resistor (RB) for
the inverting op amp configuration of Figure 29 is not
required.

b) Minimize the distance (< 0.25") from the
power-supply pins to high-frequency 0.1µF
decoupling capacitors. At the device pins, the ground
and power plane layout should not be in close
proximity to the signal I/O pins. Avoid narrow power
and ground traces to minimize inductance between
the pins and the decoupling capacitors. The
power-supply connections should always be
decoupled with these capacitors. An optional supply
decoupling capacitor (0.1µF) across the two power
supplies (for bipolar operation) will improve 2nd
harmonic distortion performance. Larger (2.2µF to
6.8µF) decoupling capacitors, effective at lower
frequency, should also be used on the main supply
pins. These capacitors may be placed somewhat
farther from the device and may be shared among
several devices in the same area of the PCB.
Heatsinking or forced airflow may be required under
extreme operating conditions. Maximum desired
junction temperature will set the maximum allowed
internal power dissipation as described below. In no
case should the maximum junction temperature be

Operating junction temperature (TJ) is given by TA +
PD • θJA. The total internal power dissipation (PD) is
the sum of quiescent power (PDQ) and additional
power dissipated in the output stage (PDL) to deliver
load power. Quiescent power is simply the specified
no-load supply current times the total supply voltage
across the part. PDL depends on the required output
signal and load; for a grounded resistive load, PDL is
at a maximum when the output is fixed at a voltage
equal to 1/2 of either supply voltage (for equal
bipolar supplies). Under this condition, PDL

c) Careful selection and placement of external
components will preserve the high frequency
performance of the OPA2652. Resistors should be
a very low reactance type. Surface-mount resistors
work best and allow a tighter overall layout. Metal
film or carbon composition axiallyleaded resistors
can also provide good high frequency performance.
Again, keep resistor leads and PCB traces as short
as possible. Never use wirewound type resistors in a
high-frequency application. Since the output pin and
inverting input pin are the most sensitive to parasitic
capacitance, always position the feedback and series
output resistor, if any, as close as possible to the
output pin. Other network components, such as
noninverting input termination resistors, should also
be placed close to the package. Where double-side
component mounting is allowed, place the feedback
resistor directly under the package on the other side
loading.
Note that it is the power in the output stage, and not
into the load, that determines internal power
dissipation.
As an example, compute the maximum TJ using an
OPA2652E (SOT23-8 package) in the circuit of
Figure 28 operating at the maximum specified
ambient temperature of +85°C and with both outputs

of the board between the output and inverting input
pins. Even with a low parasitic capacitance shunting
the external resistors, excessively high resistor
values can create significant time constants that can
degrade performance. Good axial metal film or
surface-mount resistors have approximately 0.2pF in
shunt with the resistor. For resistor values >1.5kΩ,
this parasitic capacitance can add a pole and/or zero
below 500MHz that can effect circuit operation. Keep
resistor values as low as possible consistent with
load driving considerations. The 402Ω feedback
used in the typical performance specifications is a
good starting point for design. Note that a 25Ω
feedback resistor, rather than a direct short, is
suggested for the unity gain follower application. This
effectively isolates the inverting input capacitance
from the output pin that would otherwise cause
additional peaking in the gain of +1 frequency
response.
devices to be handled as separate transmission
lines, each with respective series and shunt
terminations. If the 6dB attenuation of
a
doubly-terminated transmission line is unacceptable,
a long trace can be series-terminated at the source
end only. Treat the trace as a capacitive load in this
case and set the series resistor value as shown in
the plot of Recommended RS vs Capacitive Load
(Figure 17). This configuration will not preserve
signal integrity as well as a doubly-terminated line. If
the input impedance of the destination device is low,
there will be some signal attenuation due to the
voltage divider formed by the series output into the
terminating impedance.
e) Socketing a high-speed part like the OPA2652
is not recommended. The additional lead length
and pin-to-pin capacitance introduced by the socket
can create an extremely troublesome parasitic
network that can make it almost impossible to
achieve a smooth, stable frequency response. Best
results are obtained by soldering the OPA2652
directly onto the board.
d) Connections to other wideband devices on the
board may be made with short direct traces or
through onboard transmission lines. For short
connections, consider the trace and the input to the
next device as a lumped capacitive load. Relatively
wide traces (50mils to 100mils) should be used,
preferably with ground and power planes opened up
around them. Estimate the total capacitive load and
set RS from the plot of Recommended RS vs
Capacitive Load (Figure 17). Low parasitic capacitive
loads (< 5pF) may not need an RS since the
OPA2652 is nominally compensated to operate with
a 2pF parasitic load. Higher parasitic capacitive
loads without an RS are allowed as the signal gain
increases (increasing the unloaded phase margin) If
a long trace is required, and the 6dB signal loss
intrinsic to a doubly-terminated transmission line is

The OPA2652 is built using a very high-speed
complementary bipolar process. The internal junction
breakdown voltages are relatively low for these very
small geometry devices. These breakdowns are
reflected in the Absolute Maximum Ratings table. All
device pins are protected with internal ESD
protection diodes to the power supplies as shown in
Figure 37.
These diodes provide moderate protection to input
overdrive voltages above the supplies as well. The
protection diodes can typically support 30mA
continuous current. Where higher currents are
possible (for example, in systems with ±15V supply
parts driving into the OPA2652), current-limiting
series resistors should be added into the two inputs.

high values degrade both noise performance and
frequency response.

defined (based on board material and trace
dimensions), a matching series resistor into the trace
from the output of the OPA2652 is used as well as a
terminating shunt resistor at the input of the
destination device. Remember also that the
terminating impedance will be the parallel
combination of the shunt resistor and the input
impedance of the destination device; this total
effective impedance should be set to match the trace
impedance. The high output voltage and current
capability of the OPA2652 allows multiple destination

(1) The marketing status values are defined as follows:
ACTIVE: Product device recommended for new designs.
LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect.
NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in a new design.
PREVIEW: Device has been announced but is not in production. Samples may or may not be available.
OBSOLETE: TI has discontinued the production of the device.
(2) RoHS: TI defines "RoHS" to mean semiconductor products that are compliant with the current EU RoHS requirements for all 10 RoHS substances, including the requirement that RoHS substance
do not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, "RoHS" products are suitable for use in specified lead-free processes. TI may
reference these types of products as "Pb-Free".
RoHS Exempt: TI defines "RoHS Exempt" to mean products that contain lead but are compliant with EU RoHS pursuant to a specific EU RoHS exemption.
Green: TI defines "Green" to mean the content of Chlorine (Cl) and Bromine (Br) based flame retardants meet JS709B low halogen requirements of <=1000ppm threshold. Antimony trioxide based
flame retardants must also meet the <=1000ppm threshold requirement.
(3) MSL, Peak Temp. - The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature.
(4) There may be additional marking, which relates to the logo, the lot trace code information, or the environmental category on the device.
(5) Multiple Device Markings will be inside parentheses. Only one Device Marking contained in parentheses and separated by a "~" will appear on a device. If a line is indented then it is a continuation
of the previous line and the two combined represent the entire Device Marking for that device.
(6)
Lead finish/Ball material - Orderable Devices may have multiple material finish options. Finish options are separated by a vertical ruled line. Lead finish/Ball material values may wrap to two
lines if the finish value exceeds the maximum column width.
