Texas Instruments  OPA4377AQPWRQ1

The OPAx377-Q1 family of operational amplifiers are wide-bandwidth CMOS amplifiers that provide very low noise, low input bias current, and low offset voltage while operating on a low quiescent current of 0.76 mA (typical).

The OPAx377-Q1 op amps are optimized for low-voltage, single-supply applications. The exceptional combination of ac and dc performance make them ideal for a wide range of applications, including small signal conditioning, audio, and active filters. In addition, these parts have a wide supply range with excellent PSRR, making them attractive for applications that run directly from batteries without regulation.

The OPA377-Q1 is available in the SOT23-5 package. The dual, OPA2377-Q1, is offered in the MSOP-8 package and the quad OPA4377-Q1 is offered in the TSSOP-14 package. All versions are specified for operation from –40°C to +125°C.
