DESCRIPTION

The

operational amplifiers is designed for battery-powered

applications. These amplifiers operate on a supply voltage

as low as 1.8V. High-performance, single-supply

operation with rail-to-rail capability makes the OPA379

family useful for a wide range of applications.

In addition to microSize packages, the OPA379 family of

op amps features impressive bandwidth (90kHz), low bias

current (25pA), and low noise (80nV/√Hz) relative to the

very low quiescent current (5.5µA max).

The OPA379 (single) is available in SC70-5, SOT23-5,

and SO-8 packages. The OPA2379 (dual) comes in

SOT23-8 and SO-8 packages. The OPA4379 (quad) is

offered in a TSSOP-14 package. All versions are specified

from −40°C to +125°C.
