● AUTOMOTIVE INSTRUMENTATION

Configured internally for 5V/V gain, the INA322 offers

exceptional flexibility with user-programmable external

gain resistors. The INA322 reduces common-mode er-

ror over frequency and with CMRR remaining high up

to 3kHz, line noise and line harmonics are rejected.

DESCRIPTION

The INA322 family is a series of low cost, rail-to-rail

output, micropower CMOS instrumentation amplifiers

that offer wide-range, single-supply, as well as bipolar-

supply operation. The INA322 family provides low-

cost, low-noise amplification of differential signals with

micropower current consumption of 40µA. When shut-

down the INA322 has a quiescent current of less than

1µA. Returning to normal operations within nanosec-

onds, the shutdown feature makes the INA322 optimal

for low-power battery or multiplexing applications.

The low-power design does not compromise on band-

width or slew rate, making the INA322 ideal for driving

sampling Analog-to-Digital (A/D) converters as well as

general-purpose applications. With high precision, low

cost, and small packaging, the INA322 outperforms dis-

crete designs, while offering reliability and performance.
