Texas Instruments OPA322S
The OPAx322x series consists of single, dual, and quad-channel CMOS operational amplifiers featuring low noise and rail-to-rail inputs and outputs optimized for low-power, single-supply 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) make the OPAx322x family ideal for a wide range of applications, including signal conditioning and sensor amplification requiring high gains. Featuring low THD+N, the OPAx322x series is also excellent for consumer audio applications, particularly for single-supply systems.| Part No. | OPA322S |

DESCRIPTION
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 makes these devices well-suited for power-sensitive applications. The OPAx322S models include a shutdown mode that allow the amplifiers to be switched from normal operation to a standby current that is typically less than 0.1 μA.
