3 Description
The OPA376 family represents a new generation of low-noise operational amplifiers with e-trimTM, offering outstanding dc precision and ac performance. Rail-to- rail input and 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 (single version) is available in MicroSIZE SC70-5, SOT-23-5, and SOIC-8 packages. The OPA2376 (dual) is offered in the DSBGA-8, VSSOP-8, and SOIC-8 packages. The OPA4376 (quad) is offered in a TSSOP-14 package. All versions are specified for operation from –40°C to +125°C.
