The INA122 is a precision instrumentation amplifier
for accurate, low noise differential signal acquisition.
Its two-op-amp design provides excellent performance
with very low quiescent current, and is ideal for
portable instrumentation and data acquisition systems.
The INA122 can be operated with single power sup-
plies from 2.2V to 36V and quiescent current is a mere
60µA. It can also be operated from dual supplies. By
utilizing an input level-shift network, input common-
mode range extends to 0.1V below negative rail (single
supply ground).

to complete device failure. Precision integrated circuits may
be more susceptible to damage because very small parametric

offset adjustment. Figure 2 shows an optional circuit for
trimming the output offset voltage. The voltage applied to
the Ref terminal is added to the output signal. An op amp
buffer is used to provide low impedance at the Ref terminal
to preserve good common-mode rejection.
APPLICATION INFORMATION
Figure 1 shows the basic connections required for operation
of the INA122. Applications with noisy or high impedance
power supplies may require decoupling capacitors close to
the device pins.
The output is referred to the output reference (Ref) terminal
which is normally grounded. This must be a low-impedance
connection to ensure good common-mode rejection. A resis-
tance of 10Ω in series with the Ref pin will cause a typical
device to degrade to approximately 80dB CMR.

The 200kΩ term in equation 1 comes from the internal metal
film resistors which are laser trimmed to accurate absolute
values. The accuracy and temperature coefficient of these
resistors are included in the gain accuracy and drift specifi-
cations of the INA122.

FIGURE 2. Optional Trimming of Output Offset Voltage.
The stability and temperature drift of the external gain
setting resistor, RG, also affects gain. RG’s contribution to
gain accuracy and drift can be directly inferred from the gain
equation (1).
INPUT BIAS CURRENT RETURN PATH
The input impedance of the INA122 is extremely high—
approximately 1010Ω. However, a path must be provided for
the input bias current of both inputs. This input bias current
is approximately –10nA (current flows out of the input
terminals). High input impedance means that this input bias
current changes very little with varying input voltage.
OFFSET TRIMMING
The INA122 is laser trimmed for low offset voltage and
offset voltage drift. Most applications require no external

Input circuitry must provide a path for this input bias current
for proper operation. Figure 3 shows various provisions for an
input bias current path. Without a bias current path, the inputs
will float to a potential which exceeds the common-mode
range of the INA122 and the input amplifiers will saturate.
INPUT PROTECTION
The inputs of the INA122 are protected with internal diodes
connected to the power supply rails (Figure 4). These diodes
will clamp the applied signal to prevent it from damaging the
input circuitry. If the input signal voltage can exceed the
power supplies by more than 0.3V, the input signal current
should be limited to less than 5mA to protect the internal
clamp diodes. This can generally be done with a series input
resistor. Some signal sources are inherently current-limited
and do not require limiting resistors.
If the differential source resistance is low, the bias current
return path can be connected to one input (see the thermo-
couple example in Figure 3). With higher source impedance,
using two equal resistors provides a balanced input with
possible advantages of lower input offset voltage due to bias
current and better high-frequency common-mode rejection.
INPUT COMMON-MODE RANGE
The common-mode range for some common operating con-
ditions is shown in the typical performance curves. The
INA122 can operate over a wide range of power supply and
VREF configurations, making it impractical to provide a
comprehensive guide to common-mode range limits for all
possible conditions. The most commonly overlooked over-
load condition occurs by attempting to exceed the output
swing of A2, an internal circuit node that cannot be mea-
sured. Calculating the expected voltages at A2’s output (see
equation in Figure 4) provides a check for the most common
overload conditions.

The design of A1 and A2 are identical and their outputs can
swing to within approximately 100mV of the power supply
rails, depending on load conditions. When A2’s output is
saturated, A1 can still be in linear operation, responding to
changes in the non-inverting input voltage. This may give the
appearance of linear operation but the output voltage is invalid.

A single supply instrumentation amplifier has special design
considerations. Using commonly available single-supply op
amps to implement the two-op amp topology will not yield
equivalent performance. For example, consider the condition
where both inputs of common single-supply op amps are

equal to 0V. The outputs of both A1 and A2 must be 0V. But
any small positive voltage applied to VIN+ requires that A2’s
output must swing below 0V, which is clearly impossible
without a negative power supply.
Operation at very low supply voltage requires careful atten-
tion to ensure that the common-mode voltage remains within
its linear range.
To achieve common-mode range that extends to single-
supply ground, the INA122 uses precision level-shifting
buffers on its inputs. This shifts both inputs by approxi-
mately +0.5V, and through the feedback network, shifts A2’s
output by approximately +0.6V. With both inputs and VREF
at single-supply, A2’s output is well within its linear range.
LOW QUIESCENT CURRENT OPERATION
The INA122 maintains its low quiescent current (60µA)
while the output is within linear operation (up to 200mV
from the supply rails). When the input creates a condition
that overdrives the output into saturation, quiescent current
increases. With VO overdriven into the positive rail, the
quiescent current increases to approximately 400µA. Like-
wise, with VO overdriven into the negative rail (single
supply ground) the quiescent current increases to approxi-
mately 200µA.
+
A positive VIN causes A2’s output to swing below 0.6V.
As a result of this input level-shifting, the voltages at pin 1
and pin 8 are not equal to their respective input terminal
voltages (pins 2 and 3). For most applications, this is not
important since only the gain-setting resistor connects to
these pins.
OUTPUT CURRENT RANGE
Output sourcing and sinking current values versus the output
voltage ranges are shown in the typical performance curves.
The positive and negative current limits are not equal.
Positive output current sourcing will drive moderate to high
load impedances. Battery operation normally requires the
careful management of power consumption to keep load
impedances very high throughout the design.
LOW VOLTAGE OPERATION
The INA122 can be operated on a single power supply as
low as +2.2V (or a total of +2.2V on dual supplies). Perfor-
mance remains excellent throughout the power supply range
up to +36V (or ±18V). Most parameters vary only slightly
throughout this supply voltage range—see typical perfor-
mance curves.
