DESCRIPTION
The OPA376 family represent a new generation of
low-noise operational amplifiers with e-trim, offering
PP
outstanding dc precision and ac performance.
Rail-to-rail output, low offset (25mV max), low noise
(7.5nV/√Hz), quiescent current of 950mA 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
MicroSIZE SC70-5, SOT23-5, and SO-8 packages.
The OPA2376 (dual) is offered in the WCSP-8,
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.
