3 Description

The OPAx322-Q1 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. Specified over a wide supply range from 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 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 OPAx322-Q1 family ideal for a wide range of applications, including signal conditioning and sensor amplification requiring high gains. Featuring low THD+N, the OPAx322-Q1 family is also excellent for consumer audio applications, particularly for single-supply systems.

The OPA322-Q1 (single version) is available in 5-pin SOT-23 package, while the OPA2322-Q1 (dual version) is offered in a 8-pin VSSOP package. The OPA4322-Q1 (quad version) is available in a 14-pin TSSOP package. All versions are specified for operation from –40°C to +125°C.
