INA321E/250G4 (TEXAS INSTRUMENTS)

The INA321E/250G4 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 INA321 family provides low-noise amplification of differential signals with MicroPower current consumption of 40µA. When shutdown, the INA321 has a quiescent current of less than 1µA. Returning to normal operations within nanoseconds, the shutdown feature makes the INA321 optimal for low-power battery or multiplexing applications. Configured internally for 5V/V gain, the INA321 offers exceptional flexibility with user-programmable external gain resistors. The INA321 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 INA321 ideal for driving sampling analog-to-digital (A/D) converters as well as general-purpose applications.
