3 Description
The OPA376 family represents a new generation of
low-noise operational amplifiers with e-trim™, offering
outstanding dc precision and ac performance. Rail-to-
rail input and output, low offset (25 μV, maximum),
low noise (7.5 nV/√Hz), quiescent current of 950 μA
(maximum), and a 5.5-MHz 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, SOT-23-5, and SOIC-8
packages. The OPA2376 (dual) is offered in the
DSBGA-8, VSSOP-8, and SOIC-8 packages. The
OPA4376 (quad) is offered in a TSSOP-14 package.
All versions are specified for operation from –40°C to
+125°C.
