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.
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.
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.
