1.1nV/√Hz Noise, Low Power, Precision
Operational Amplifier in Small DFN-8 Package

FEATURES
DESCRIPTION
23
•
LOW VOLTAGE NOISE: 1.1nV/√Hz at 1kHz
The OPA211 series of precision operational
amplifiers achieves very low 1.1nV/√Hz noise density
with a supply current of only 3.6mA. This series also
offers rail-to-rail output swing, which maximizes
dynamic range.
•
INPUT VOLTAGE NOISE:
80nVPP (0.1Hz to 10Hz)
•
•
•
•
•
•
THD+N: –136dB (G = 1, f = 1kHz)
OFFSET VOLTAGE: 125µV (max)
OFFSET VOLTAGE DRIFT: 0.35µV/°C (typ)
LOW SUPPLY CURRENT: 3.6mA/Ch (typ)
UNITY-GAIN STABLE
The extremely low voltage and low current noise,
high speed, and wide output swing of the OPA211
series make these devices an excellent choice as a
loop filter amplifier in PLL applications.
GAIN BANDWIDTH PRODUCT:
80MHz (G = 100)
45MHz (G = 1)
In precision data acquisition applications, the
OPA211 series of op amps provides 700ns settling
time to 16-bit accuracy throughout 10V output swings.
This ac performance, combined with only 125µV of
offset and 0.35µV/°C of drift over temperature, makes
the OPA211 ideal for driving high-precision 16-bit
analog-to-digital converters (ADCs) or buffering the
output of high-resolution digital-to-analog converters
(DACs).
•
•
•
SLEW RATE: 27V/µs
16-BIT SETTLING: 700ns
WIDE SUPPLY RANGE:
±2.25V to ±18V, +4.5V to +36V
•
•
•
RAIL-TO-RAIL OUTPUT
The OPA211 series is specified over
a wide
OUTPUT CURRENT: 30mA
dual-power supply range of ±2.25V to ±18V, or for
single-supply operation from +4.5V to +36V.
DFN-8 (3mm × 3mm), MSOP-8, AND SO-8
The OPA211 is available in the small DFN-8 (3mm ×
3mm), MSOP-8, and SO-8 packages. A dual version,
the OPA2211, is available in the DFN-8 (3mm ×
3mm) or an SO-8 PowerPAD™ package. This series
of op amps is specified from TA = –40°C to +125°C.

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.

INPUT PROTECTION
NOISE PERFORMANCE
The input terminals of the OPA211 are protected from
excessive differential voltage with back-to-back
diodes, as shown in Figure 45. In most circuit
applications, the input protection circuitry has no
consequence. However, in low-gain or G = 1 circuits,
fast ramping input signals can forward bias these
diodes because the output of the amplifier cannot
respond rapidly enough to the input ramp. This effect
is illustrated in Figure 32 of the Typical
Characteristics. If the input signal is fast enough to
create this forward bias condition, the input signal
current must be limited to 10mA or less. If the input
signal current is not inherently limited, an input series
resistor can be used to limit the signal input current.
This input series resistor degrades the low-noise
performance of the OPA211, and is discussed in the
Noise Performance section of this data sheet.
Figure 46 shows total circuit noise for varying source
impedances with the op amp in
a unity-gain
configuration (no feedback resistor network, and
therefore no additional noise contributions). Two
different op amps are shown with total circuit noise
calculated. The OPA211 has very low voltage noise,
making it ideal for low source impedances (less than
2kΩ). A similar precision op amp, the OPA227, has
somewhat higher voltage noise but lower current
noise. It provides excellent noise performance at
moderate source impedance (10kΩ to 100kΩ). Above
100kΩ, a FET-input op amp such as the OPA132
(very low current noise) may provide improved
performance. The equation in Figure 46 is shown for
the calculation of the total circuit noise. Note that en =
voltage noise, In = current noise, RS = source
impedance, k = Boltzmann’s constant = 1.38 × 10–23
J/K, and T is temperature in degrees Kelvin.

SHUTDOWN
The shutdown (enable) function of the OPA211 is
referenced to the positive supply voltage of the
operational amplifier. A valid high disables the op
amp. A valid high is defined as (V+) – 0.35V of the
positive supply applied to the shutdown pin. A valid
low is defined as (V+) – 3V below the positive supply
pin. For example, with VCC at ±15V, the device is
enabled at or below 12V. The device is disabled at or
above 14.65V. If dual or split power supplies are
used, care should be taken to ensure the valid high
or valid low input signals are properly referred to the
positive supply voltage. This pin must be connected
to a valid high or low voltage or driven, and not left
open-circuit. The enable and disable times are
provided in the Typical Characteristics section (see
Figure 41 through Figure 43). When disabled, the
output assumes a high-impedance state.

OPA227 in Unity-Gain Buffer Configuration
BASIC NOISE CALCULATIONS
Design of low-noise op amp circuits requires careful
consideration of
a
variety of possible noise
contributors: noise from the signal source, noise
generated in the op amp, and noise from the
feedback network resistors. The total noise of the
circuit is the root-sum-square combination of all noise
components.
The resistive portion of the source impedance
produces thermal noise proportional to the square
root of the resistance. This function is plotted in
Figure 46. The source impedance is usually fixed;
consequently, select the op amp and the feedback
resistors to minimize the respective contributions to
the total noise.

Therefore, the lowest noise op amp for a given
application depends on the source impedance. For
low source impedance, current noise is negligible and
voltage noise generally dominates. For high source
impedance, current noise may dominate.
a
configuration (no feedback resistor network, and
therefore no additional noise contributions). The
operational amplifier itself contributes both a voltage
noise component and a current noise component.
The voltage noise is commonly modeled as a
time-varying component of the offset voltage. The
current noise is modeled as the time-varying
component of the input bias current and reacts with
the source resistance to create a voltage component
of noise.
Figure 47 illustrates both inverting and noninverting
op amp circuit configurations with gain. In circuit
configurations with gain, the feedback network
resistors also contribute noise. The current noise of
the op amp reacts with the feedback resistors to
create additional noise components. The feedback
resistor values can generally be chosen to make
these noise sources negligible. The equations for
total noise are shown for both configurations.

TOTAL HARMONIC DISTORTION
MEASUREMENTS
Audio Precision System Two distortion/noise
analyzer, which greatly simplifies such repetitive
measurements. The measurement technique can,
however, be performed with manual distortion
measurement instruments.
OPA211 series op amps have excellent distortion
characteristics. THD + Noise is below 0.0002% (G =
+1, VOUT = 3VRMS) throughout the audio frequency
range, 20Hz to 20kHz, with a 600Ω load.
ELECTRICAL OVERSTRESS
The distortion produced by OPA211 series op amps
is below the measurement limit of many commercially
available distortion analyzers. However, a special test
circuit illustrated in Figure 48 can be used to extend
the measurement capabilities.
Designers often ask questions about the capability of
an operational amplifier to withstand electrical
overstress. These questions tend to focus on the
device inputs, but may involve the supply voltage pins
or even the output pin. Each of these different pin
functions have electrical stress limits determined by
the voltage breakdown characteristics of the
particular semiconductor fabrication process and
specific circuits connected to the pin. Additionally,
internal electrostatic discharge (ESD) protection is
built into these circuits to protect them from
accidental ESD events both before and during
product assembly.
Op amp distortion can be considered an internal error
source that can be referred to the input. Figure 48
shows a circuit that causes the op amp distortion to
be 101 times greater than that normally produced by
the op amp. The addition of R3 to the otherwise
standard noninverting amplifier configuration alters
the feedback factor or noise gain of the circuit. The
closed-loop gain is unchanged, but the feedback
available for error correction is reduced by a factor of
101, thus extending the resolution by 101. Note that
the input signal and load applied to the op amp are
the same as with conventional feedback without R3.
The value of R3 should be kept small to minimize its
effect on the distortion measurements.
It is helpful to have a good understanding of this
basic ESD circuitry and its relevance to an electrical
overstress event. See Figure 49 for an illustration of
the ESD circuits contained in the OPA211 (indicated
by the dashed line area). The ESD protection circuitry
involves several current-steering diodes connected
from the input and output pins and routed back to the
internal power-supply lines, where they meet at an
absorption device internal to the operational amplifier.
This protection circuitry is intended to remain inactive
during normal circuit operation.
Validity of this technique can be verified by
duplicating measurements at high gain and/or high
frequency where the distortion is within the
measurement capability of the test equipment.

Figure 49. Equivalent Internal ESD Circuitry and Its Relation to a Typical Circuit Application
An ESD event produces short duration,
a
Figure 49 depicts a specific example where the input
voltage, VIN, exceeds the positive supply voltage
(+VS) by 500mV or more. Much of what happens in
the circuit depends on the supply characteristics. If
+VS can sink the current, one of the upper input
steering diodes conducts and directs current to +VS.
Excessively high current levels can flow with
increasingly higher VIN. As a result, the datasheet
specifications recommend that applications limit the
input current to 10mA.
high-voltage pulse that is transformed into a short
duration, high-current pulse as it discharges through
a semiconductor device. The ESD protection circuits
are designed to provide a current path around the
operational amplifier core to prevent it from being
damaged. The energy absorbed by the protection
circuitry is then dissipated as heat.
When an ESD voltage develops across two or more
of the amplifier device pins, current flows through one
or more of the steering diodes. Depending on the
path that the current takes, the absorption device
may activate. The absorption device has a trigger, or
threshold voltage, that is above the normal operating
voltage of the OPA211 but below the device
breakdown voltage level. Once this threshold is
exceeded, the absorption device quickly activates
and clamps the voltage across the supply rails to a
safe level.
If the supply is not capable of sinking the current, VIN
may begin sourcing current to the operational
amplifier, and then take over as the source of positive
supply voltage. The danger in this case is that the
voltage can rise to levels that exceed the operational
amplifier absolute maximum ratings. In extreme but
rare cases, the absorption device triggers on while
+VS and –VS are applied. If this event happens, a
direct current path is established between the +VS
and –VS supplies. The power dissipation of the
absorption device is quickly exceeded, and the
extreme internal heating destroys the operational
amplifier.
When the operational amplifier connects into a circuit
such as that illustrated in Figure 49, the ESD
protection components are intended to remain
inactive and not become involved in the application
circuit operation. However, circumstances may arise
where an applied voltage exceeds the operating
voltage range of a given pin. Should this condition
occur, there is a risk that some of the internal ESD
protection circuits may be biased on, and conduct
current. Any such current flow occurs through
steering diode paths and rarely involves the
absorption device.
Another common question involves what happens to
the amplifier if an input signal is applied to the input
while the power supplies +VS and/or –VS are at 0V.
Again, it depends on the supply characteristic while at
0V, or at a level below the input signal amplitude. If

most likely will not operate normally. If the supplies
are low impedance, then the current through the
steering diodes can become quite high. The current
level depends on the ability of the input source to
deliver current, and any resistance in the input path.
DFN packages are physically small, and have a
smaller routing area, improved thermal performance,
and improved electrical parasitics. Additionally, the
absence of external leads eliminates bent-lead
issues.
The DFN package can be easily mounted using
standard printed circuit board (PCB) assembly
techniques. See Application Note QFN/SON PCB
Attachment (SLUA271) and Application Report Quad
Flatpack No-Lead Logic Packages (SCBA017), both
available for download at www.ti.com.
THERMAL CONSIDERATIONS
A primary issue with all semiconductor devices is
junction temperature (TJ). The most obvious
consideration is assuring that TJ never exceeds the
absolute maximum rating specified for the device.
However, addressing device thermal dissipation has
benefits beyond protecting the device from damage.
Even modest increases in junction temperature can

Understanding the power generated by the device
within the specific application and assessing the
thermal effects on the error tolerance lead to a better
DFN LAYOUT GUIDELINES
The exposed leadframe die pad on the DFN package
should be soldered to a thermal pad on the PCB. A
mechanical drawing showing an example layout is
attached at the end of this data sheet. Refinements to
this layout may be necessary based on assembly
process requirements. Mechanical drawings located
at the end of this data sheet list the physical
dimensions for the package and pad. The five holes
in the landing pattern are optional, and are intended
for use with thermal vias that connect the leadframe
die pad to the heatsink area on the PCB.
understanding
of
system
performance
and
thermal-dissipation needs. For dual-channel products,
the worst-case power resulting from both channels
must be determined. Products with a thermal pad
(DFN and PowerPAD devices) provide the best
thermal conduction away from the junction; see the
Thermal Resistance from Junction to Pad parameter
(θJP) in the Electrical Characteristics section. The use
of packages with a thermal pad improves thermal
dissipation. The device achieves its optimal
performance through careful board and system
design that considers characteristics such as board
thickness, metal layers, component spacing, airflow,
and board orientation. Refer to these application
notes (available for download at www.ti.com) for
additional details: SZZA017A, SCBA017, and
SPRA953A. For unusual loads and signals, see
SBOA022.
Soldering the exposed pad significantly improves
board-level reliability during temperature cycling, key
push, package shear, and similar board-level tests.
Even with applications that have low-power
dissipation, the exposed pad must be soldered to the
PCB to provide structural integrity and long-term
reliability.
DFN PACKAGE
The OPA211 is offered in an DFN-8 package (also
known as SON). The DFN package is a QFN
package with lead contacts on only two sides of the
bottom of the package. This leadless package
maximizes board space and enhances thermal and
electrical characteristics through an exposed pad.

CONSIDERATIONS
example thermal land pattern mechanical drawing
is attached to the end of this data sheet.
3. Additional vias may be placed anywhere along
the thermal plane outside of the thermal pad area
to help dissipate the heat generated by the
OPA2211 SO-8. These additional vias may be
larger than the 13-mil diameter vias directly under
the thermal pad. They can be larger because
they are not in the thermal pad area to be
soldered; thus, wicking is not a problem.
The OPA2211 is available in a thermally-enhanced
SO-8 PowerPAD package. This package is
constructed using a downset leadframe upon which
the die is mounted, as Figure 50(a) and Figure 50(b)
illustrate. This arrangement results in the lead frame
being exposed as a thermal pad on the underside of
the package, as shown in Figure 50(c). This thermal
pad has direct thermal contact with the die; thus,
excellent thermal performance is achieved by
providing a good thermal path away from the thermal
pad.
4. Connect all holes to the internal plane that is at
the same voltage potential as the V– pin.
5. When connecting these holes to the internal
plane, do not use the typical web or spoke via
connection methodology. Web connections have
a high thermal resistance connection that is
useful for slowing the heat transfer during
soldering operations. This configuration makes
the soldering of vias that have plane connections
easier. In this application, however, low thermal
resistance is desired for the most efficient heat
transfer. Therefore, the holes under the OPA2211
The PowerPAD package allows for both assembly
and thermal management in one manufacturing
operation. During the surface-mount solder operation
(when the leads are being soldered), the thermal pad
must be soldered to a copper area underneath the
package. Through the use of thermal paths within this
copper area, heat can be conducted away from the
package into either
a ground plane or other
heat-dissipating device. Soldering the PowerPAD to
the printed circuit board (PCB) is always required,
even with applications that have low power
dissipation. This technique provides the necessary
thermal and mechanical connection between the lead
frame die pad and the PCB.
PowerPAD

connection to the internal plane with a complete
connection around the entire circumference of the
plated-through hole.
6. The top-side solder mask should leave the
terminals of the package and the thermal pad
area with its six holes exposed. The bottom-side
solder mask should cover the holes of the
thermal pad area. This masking prevents solder
from being pulled away from the thermal pad
area during the reflow process.
The PowerPAD must be connected to the most
negative supply voltage on the device (V–).
1. Prepare the PCB with a top-side etch pattern.
There should be etching for the leads as well as
etch for the thermal pad.
2. Place recommended holes in the area of the
thermal pad. Ideal thermal land size and thermal
via patterns for the SO-8 DDA package can be
seen in the technical brief, PowerPAD
7. Apply solder paste to the exposed thermal pad
area and all of the IC terminals.
8. With these preparatory steps in place, simply
place the OPA2211 SO-8 IC in position and run
the chip through the solder reflow operation as
any standard surface-mount component. This
preparation results in a properly installed part.

TI is not responsible or liable for any such statements.
Buyer acknowledges and agrees that it is solely responsible for compliance with all legal, regulatory and safety-related requirements
concerning its products, and any use of TI components in its applications, notwithstanding any applications-related information or support
that may be provided by TI. Buyer represents and agrees that it has all the necessary expertise to create and implement safeguards which
anticipate dangerous consequences of failures, monitor failures and their consequences, lessen the likelihood of failures that might cause
harm and take appropriate remedial actions. Buyer will fully indemnify TI and its representatives against any damages arising out of the use
of any TI components in safety-critical applications.
In some cases, TI components may be promoted specifically to facilitate safety-related applications. With such components, TI’s goal is to
help enable customers to design and create their own end-product solutions that meet applicable functional safety standards and
requirements. Nonetheless, such components are subject to these terms.
No TI components are authorized for use in FDA Class III (or similar life-critical medical equipment) unless authorized officers of the parties
have executed a special agreement specifically governing such use.
Only those TI components which TI has specifically designated as military grade or “enhanced plastic” are designed and intended for use in
military/aerospace applications or environments. Buyer acknowledges and agrees that any military or aerospace use of TI components
which have not been so designated is solely at the Buyer's risk, and that Buyer is solely responsible for compliance with all legal and
regulatory requirements in connection with such use.
TI has specifically designated certain components as meeting ISO/TS16949 requirements, mainly for automotive use. In any case of use of
non-designated products, TI will not be responsible for any failure to meet ISO/TS16949.
