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.
