DESCRIPTION
The INA332 and INA2332 are rail-to-rail output, low-power
CMOS instrumentation amplifiers that offer wide range, single-
supply, and bipolar-supply operation. Using a special manu-
facturing flow, the INA332 family provides the lowest cost
available, while still achieving low-noise amplification of dif-
ferential signals with low quiescent current of 415
μ
A (drop-
ping to 0.01
μ
A when shutdown). Returning to normal opera-
tion within microseconds, this INA can be used for battery or
multichannel applications.
Configured internally in a gain of 5V/V, the INA332 offers
flexibility in higher gains by choosing external resistors.

AUTOMOTIVE INSTRUMENTATION
The INA332 rejects line noise and its harmonics because
common-mode error remains low even at higher frequencies.
High bandwidth and slew rate make the INA332 ideal for
directly driving sampling Analog-to-Digital (A/D) converters
as well as general-purpose applications.
With high precision, low cost, and small packages, the
INA332 outperforms discrete designs.
Additionally, because they are specified for wide temperature
range of –55
°
C to +125
°
C and operating range of –65
°
C to
+150
°
C, the INA331 family can be used in demanding
industrial and automotive environments.
