DESCRIPTION
11
The INA2132 is a dual low power, unity-gain difference amplifier offering excellent value at very low
cost. Each channel consists of a precision op amp with
a laser-trimmed precision resistor network, providing
accurate gain and high common-mode rejection. Excellent TCR tracking of the resistors maintains gain
accuracy and common-mode rejection over temperature. The internal op amp’s common-mode range
extends to the negative supply—ideal for single-supply applications.
The difference amplifier is the foundation of many
commonly used circuits. The INA2132 provides this
circuit function without using an expensive precision
resistor network. The INA2132 is available in the
SO-14 surface-mount package and is specified for
operation over the extended industrial temperature
range, –40°C to +85°C.
A single version of this product with similar specifications is also available. See the INA132 data sheet
for details.

APPLICATIONS INFORMATION
In the case where VREF is grounded, the equation simplifies to:
Figure 1 shows the basic connections required for operation
of the INA2132. Power supply bypass capacitors should be
connected close to the device pins.
2 • (V–) < VCM < 2 • ((V+) – 1)
For more information, see the typical performance curve titled
“Input Common-Mode Voltage Range vs Output Voltage.”
The differential input signal is connected to pins 2 and 3 (or
pins 6 and 5) as shown. The source impedances connected to
the inputs must be nearly equal to assure good commonmode rejection. An 8Ω mismatch in source impedance will
degrade the common-mode rejection of a typical device to
approximately 80dB. Gain accuracy will also be slightly
affected. If the source has a known impedance mismatch, an
additional resistor in series with one input can be used to
preserve good common-mode rejection.
OPERATING VOLTAGE
The INA2132 operates from single (+2.7V to +36V) or dual
(±1.35V to ±18V) supplies with excellent performance.
Specifications are production tested with +5V and ±15V
supplies. Most behavior remains unchanged throughout the
full operating voltage range. Parameters which vary significantly with operating voltage are shown in the Typical
Performance Curves.
Do not interchange pins 3 and 14 (or pins 5 and 8) or pins
2 and 12 (or pins 6 and 10), even though nominal resistor
values are equal. These resistors are laser-trimmed for precise resistor ratios to achieve accurate gain and highest
CMRR. Interchanging these pins may not provide specified
performance. As shown in Figure 1, sense line should be
connected as close to the load as possible.
The INA2132 can accurately measure differential signals
that are beyond the power supply rails. Linear commonmode range extends to twice the negative power supply
voltage and nearly twice the positive power supply voltage.
Output phase reversal does not occur when the inputs to the
internal operational amplifier are overloaded to either rail.
See typical performance curve, “Common-Mode Range vs
Output Voltage.”
NOTE: Pin numbers in parentheses ( ) refer to channel B.
OFFSET VOLTAGE TRIM
V+
V–
1µF
1µF
The INA2132 is laser-trimmed for low offset voltage and
drift. Most applications require no external offset adjustment. Figure 2 shows an optional circuit for trimming the
output offset voltage. The output is referred to the output
reference terminal (pin 14 or pin 8), which is normally
grounded. A voltage applied to the Ref terminal will be
summed with the output signal. This can be used to null
offset voltage. The source impedance of a signal applied to
the Ref terminal should be less than 8Ω to maintain good
common-mode rejection. To assure low impedance at the
Ref terminal, the trim voltage can be buffered with an op
amp, such as the OPA277.

To ensure valid operation of the differential amplifier, please

limit the common-mode voltage inputs to:

CAPACITIVE LOAD DRIVE CAPABILITY
directly adjacent on the top and bottom sides of a circuit
board. Stray coupling then produces a common-mode signal
which is rejected by the INA2132’s input.
The INA2132 can drive large capacitive loads, even at low
supplies. It is stable with a 10nF load. Refer to the “SmallSignal Step Response” and “Settling Time vs Load Capacitance” typical performance curves.

CHANNEL CROSSTALK
11
The two channels of the INA2132 are completely independent, including all bias circuitry. At dc and low frequency,
there is virtually no signal coupling between channels.
Crosstalk increases with frequency and is dependent on
source impedance and signal characteristics. See the typical
performance curve “Channel Separation vs Frequency” for
more information.
INA2132
12 (10)
2 (6)
–In
13 (9)
Most crosstalk is produced by capacitive coupling of signals
from one channel to the input section of the other channel.
To minimize coupling, separate the input traces as far as
practical from any signals associated with the opposite
channel. A grounded guard trace surrounding the inputs
helps reduce stray coupling between channels. Run the
differential inputs of each channel parallel to each other or

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
