INA2321EA/250

The INA2321EA/250 is a Micropower single-supply CMOS Instrumentation Amplifier with rail-to-rail output. It offers wide-range, single-supply, as well as bipolar-supply operation. The INA2321 family provides low-noise amplification of differential signals with micropower current consumption of 40µA. When shutdown, the INA2321 has a quiescent current of less than 1µA. Returning to normal operations within nanoseconds, the shutdown feature makes the INA2321 optimal for low-power battery or multiplexing applications. Configured internally for 5V/V gain, the INA2321 offers exceptional flexibility with user-programmable external gain resistors. The INA2321 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 INA2321 ideal for driving sample analog-to-digital (A/D) converters as well as general-purpose applications.
