ꢀ AUTOMOTIVE INSTRUMENTATION

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

tional flexibility with user-programmable external gain resis-

tors. The INA322 reduces common-mode error over fre-

quency 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 shutdown the INA322 has a quiescent current

of less than 1µA. Returning to normal operations within

microseconds, the shutdown feature makes the INA322

optimal for low-power battery or multiplexing applications.

The low-power design does not compromise on bandwidth or

slew rate, making the INA322 ideal for driving sampling Ana-

log-to-Digital (A/D) converters as well as general-purpose

applications. With high precision, low cost, and small packag-

ing, the INA322 outperforms discrete designs, while offering

reliability and performance.
