OPA376

低噪声、低 IQ 精密运算放大器

The family represents a new 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 _Micro_SIZE 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.
