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. 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.

(1) Stresses above these ratings may cause permanent damage.
Exposure to absolute maximum conditions for extended periods
may degrade device reliability. These are stress ratings only, and
functional operation of the device at these or any other conditions
beyond those specified is not supported.
(2) Input terminals are diode-clamped to the power-supply rails.
Input signals that can swing more than 0.5V beyond the supply
rails should be current-limited to 10mA or less.
(3) Short-circuit to ground, one amplifier per package.

This integrated circuit can be damaged by ESD. Texas
Instruments recommends that all integrated circuits be
handled with appropriate precautions. Failure to observe
proper handling and installation procedures can cause damage.
ESD damage can range from subtle performance degradation to
complete device failure. Precision integrated circuits may be more
susceptible to damage because very small parametric changes could
cause the device not to meet its published specifications.
