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 (25μV max), low noise
(7.5nV/√Hz), quiescent current of 950μA 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-Q1 (single version) is available in
MicroSIZE SC70-5, SOT23-5, and SO-8 packages.
The OPA2376-Q1 (dual) is offered in the SO-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.
