3 Description

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 lowvoltage,

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.
