DESCRIPTION
LOW NOISE: 2.8µV
PP
The OPA379 family of micropower, low-voltage
D
D
D
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).

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.
