OPERATIONAL AMPLIFIERS

FEATURES

DESCRIPTION

•

LOW NOISE: 2.8µV_PP(0.1Hz - 10Hz)

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

(10µV max) makes the OPA379 family useful for a

wide range of applications.

microPower: 5.5µA (max)

LOW OFFSET VOLTAGE: 1.5mV (max)

DC PRECISION:

–

CMRR: 100dB

PSRR: 2µV/V

A_OL: 120dB

In addition to microSize packages, the OPA379 family

of op amps features impressive bandwidth (90kHz),

low bias current (5pA), and low noise (80nV/√Hz)

relative to the very low quiescent current (5.5µA

max).

•

WIDE SUPPLY VOLTAGE RANGE: 1.8V to 5.5V

microSize PACKAGES:

–

SC70-5, SOT23-5, SOT23-8, SO-8, TSSOP-14

APPLICATIONS

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.
