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.
