Texas Instruments' OPA322 series consists of single, dual, and quad-channel CMOS operational amplifiers featuring low noise and rail-to-rail inputs/outputs optimized for low-power, single-supply applications. Specified over a wide supply range of 1.8 V to 5.5 V, the low quiescent current of only 1.5 mA per channel make these devices well-suited for power-sensitive applications. The combination of very low noise (8.5 nV/√Hz at 1 kHz), high gain-bandwidth (20 MHz), and fast slew rate (10 V/µs) makes the OPA322 family ideal for a wide range of applications, including signal conditioning and sensor amplification requiring high gains.
