Description

The OPA379 family of micropower, low-voltage operational amplifiers is designed for battery-powered applications. These amplifiers operate on a supply voltage as low as 1.8V (±0.9V). High-performance, single-supply operation with rail-to-rail capability (w1i0dmeVramngaex)ofmaapkpeliscatthioensO.PA379 family useful for a

In addition to microSize packages, the OPA379 family of op amps features impressive bandwidth (()kHz), low bias current (5pA), and low noise (80nV/√Hz) relative to the very low quiescent current (5.5mA 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.
