DESCRIPTION
The OPA377 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
0.76mA (typ).
The OPA377 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 is available in the SC70-5, SOT23-5,
and SO-8 packages. The dual OPA2377 is offered in
the SO-8 and MSOP-8, and the quad OPA4377 in the
TSSOP-14 packages. All versions are specified for
operation from –40°C to +125°C.
