3 Description
The OPA376-Q1 family represent a new generation
of low-noise operational amplifiers with e-trim™,
offering outstanding dc precision and ac performance.
Rail-to-rail 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-Q1 (single version) is available in
MicroSIZE SC70-5, SOT23-5, and SOIC-8 packages.
The OPA2376-Q1 (dual) is offered in the SOIC-8 and
VSSOP-8 package. The OPA4376-Q1 (quad) is
offered in a TSSOP-14 package. All versions are
specified for operation from –40°C to +125°C.
