The OPA322-Q1 family 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, and with a low quiescent current of only 1.5 mA per channel, these devices are well-suited for power-sensitive applications.
The combination of very low noise (8.5 nV/√Hz at 1kHz), high gain-bandwidth (20 MHz), and fast slew rate (10 V/μs) make the OPA322-Q1 family ideal for a wide range of applications, including signal conditioning and sensor amplification requiring high gains. Featuring low THD+N, the OPA322-Q1 family is also excellent for consumer audio applications, particularly for single-supply systems.
The OPAx322S-Q1 models include a shutdown mode allowing the amplifiers to switch from normal operation to a standby current that is typically less than 0.1 µA.
The OPA322-Q1 (single version) is available in SOT23-5 and SOT23-6, whereas the OPA2322 (dual version) comes in MSOP-8, MSOP-10, SO-8, and DFN-8 packages. The quad versions OPA4322 come in TSSOP-14 and TSSOP-16 packages. The specification on all versions is for operation from –40°C to 125°C.
