3 Description
The OPAx376-Q1 family represents a new generation
of low-noise e-trim™ operational amplifiers, offering
outstanding dc precision and ac performance. Rail-torail
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 device very
attractive for a variety of precision and portable
applications. In addition, this device has a reasonably
wide supply range with excellent PSRR, making the
OPA376-Q1 an excellent choice 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.
