DESCRIPTION

LOW NOISE: 2.8µV

The OPA379 family of micropower, low-voltage

microPower: 5.5µA (max)

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.

LOW OFFSET VOLTAGE: 1.5mV (max)

DC PRECISION:

− CMRR: 100dB

− PSRR: 2µV/V

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).

− A : 120dB

WIDE SUPPLY VOLTAGE RANGE: 1.8V to 5.5V

microSize PACKAGES

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.
