OPA376AIDRG4

低噪声，低静态电流，精密运算放大器电子微调系列 Low-Noise, Low Quiescent Current, Precision Operational Amplifier e-trim Series

DESCRIPON

The OPA376 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 25mV max, low noise 7.5nV/√Hz, quiescent current of 950mA max, and a 5.5MHz 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, SOT23-5, and SO-8 packages.

The OPA2376 dual is offered in the WCSP-8, MSOP-8, and SO-8 packages. The OPA4376 quad

is offered in a TSSOP-14 package. All versions are specified for operation from –40°C to +125°C.
