Dual, 700MHz, Voltage-Feedback  
OPERATIONAL AMPLIFIER  
FEATURES  
DESCRIPTION  
WIDEBAND BUFFER: 700MHz, G = +1  
WIDEBAND LINE DRIVER: 200MHz, G = +2  
HIGH OUTPUT CURRENT: 140mA  
LOW SUPPLY CURRENT: 5.5mA/Ch  
ULTRA-SMALL PACKAGE: SOT23-8  
LOW dG/dφ: 0.05%/0.03°  
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 50load.  
For the circuit of Figure 28, the total effective load  
will be 100|| 804. 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 (174) 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 201source 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 (57.6) used  
for testing gives a 50input load. A resistor (205)  
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 50with a resistor to  
ground and the output impedance is set to 50with  
a series output resistor.

Figure 31 shows a single OPA2652 implementing a  
sixth-order bandpass filter. This filter cascades two  
second-order Sallen-Key sections with transmission

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 25resistor, 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 200and 1.5k.  
Below 200, the feedback network presents  
additional output loading that can degrade the  
harmonic distortion performance of the OPA2652.  
Above 1.5k, 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 50for 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 50source 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 200to 1.5krange. 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 300. 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 < 300keeps this  
pole above 250MHz. By itself, this constraint implies  
that the feedback resistor RF can increase to several  
kat 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 50source impedance, yielding an effective  
driving impedance of 50|| 57.6= 26.8. 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).

noninverting gain of

a
1
(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  
looking out of the inverting node, the output DC

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 429. Combining this in parallel with the  
feedback resistor gives 208, which is close to the  
RB = 205used 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 <300, 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  
50or ±2.5V into 100without 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 100load 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 (5) in the power-supply line will protect  
against this. Always place the 0.1µF decoupling  
capacitor directly on the supply pins.  
network;  
in  
the  
noninverting  
configuration  
(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 (205) 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 300. 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.

unintentional bandlimiting. To reduce unwanted  
capacitance, a window around the signal I/O pins

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

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  
driving 2.5VDC into a grounded 100load.  
PD = 10V 15.5mA + 2 [52/(4 [100804])] =  
296mW  
Maximum TJ = +85°C + (0.30W 150°C/W) = 130°C

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 >1.5k,  
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 402feedback  
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  
Input and ESD Protection  
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.  
Keep these resistor values as low as possible since  
high values degrade both noise performance and  
frequency response.  
acceptable, implement  
a
matched impedance  
transmission line using microstrip or stripline  
techniques (consult an ECL design handbook for  
microstrip and stripline layout techniques). A 50Ω  
environment is normally not necessary on board, and  
in fact, a higher impedance environment will improve  
distortion as shown in the distortion versus load  
plots. With a characteristic board trace impedance  
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
