DESCRIPTION
The OPA376 family represent a new generation of
low-noise operational amplifiers. Rail-to-rail input, low
offset (5μV typ), low noise (7.5nV/√Hz), quiescent
current less than 1mA max, and a 5.5MHz bandwidth
make this part very attractive for a variety of precision
and portable applications. In addition, this device has
a reasonably wide supply range with excellent PSRR,
making it attractive for applications that run directly
from batteries without regulation.
The OPA376 (single version) is available in
MicroSIZE
SC70-5, SOT23-5, and SO-8 packages.
The OPA2376 (dual) is offered in the MSOP-8 and
SO-8 packages. The OPA4376 (quad) is offered in a
TSSOP-14 package. All versions are specified for
operation from –40°C to +125°C.

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.

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.
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.
Short-circuit to ground one amplifier per package.
