OPAx376 Operational Amplifiers

OPAx376 Operational Amplifiers

Texas Instruments' OPA376 family represents a generation of low-noise operational amplifiers with e-trim, 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.
