3 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 (25 μV maximum), low noise (7.5 nV/√Hz), quiescent current of 950 μA (maximum), and a 5.5-MHz 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 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.
