OPA322-Q1 - Automotive 20MHz Low-Noise 1.8V RRI/O CMOS Operational Amplifier

Updated : 2020-01-09 14:20:40
Description

The OPAx322-Q1 series consists of single-, dual-, and quad-channel CMOS operationalamplifiers 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 lowquiescent current of only 1.5 mA per channel makes these devices well-suited for power-sensitiveapplications.

The combination of very-low noise (8.5 nV√Hz at 1 kHz), high-gainbandwidth (20 MHz), and fast slew rate (10 V/µs) make the OPAx322-Q1 family ideal for a wide rangeof 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 a14-pin TSSOP package. All versions are specified for operation from –40°C to +125°C.
