Description：

The OPA376 family represents a new generation oflow-noise operational amplifiers with e-trim TM, offeringoutstanding dc precision and ac performance. Rail-to-rail input and output, low offset (25 uV, maximum),low noise (7.5 nV/Hz), quiescent current of 950 uA(maximum), and a 5.5-MHz bandwidth make this partvery attractive for a variety of precision and portableapplications. In addition, this device has a reasonablywide supply range with excellent PSRR, making itattractive for applicationsthat run directly frombatteries without regulation.

The OPA376 (singleversion)is availableinMicroSIZESC70-5,SOT-23-5,SOIC-8andThe OPA2376 (dual) is offered in thepackages.DSBGA-8, VSSOP-8, and SOIC-8 packages. TheOPA4376 (quad) is offered in a TSSOP-14 package.All versions are specified for operation from -40°C to

+125°C。
