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.
R1 Configured internally for 5V/V gain, the INA322 offers exceptional flexibility with user-programmable external gain resistors.
The INA322 reduces common-mode error over frequency 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 Analog-to-Digital (A/D) converters as well as general-purpose applications.
With high precision, low cost, and small packaging, the INA322 outperforms discrete designs, while offering reliability and performance.
