Product Summary

The OPA37FZ is a low noise, low quiescent current, operational amplifier. The OPA37FZ represents a new generation of low-noise operational amplifier. Rail-to-rail input, low offset (5μV typ), low noise (7.5nV/√Hz), quiescent current less than 1mA max, and a 5.5MHz bandwidth make this part very attractive for a variety of precision and portable applications. In addition, the OPA37FZ has a reasonably wide supply range with excellent PSRR, making it attractive for applications that run directly from batteries without regulation. The applications of the device include precision instrumentation, data acquisition, test equipment, professional audio equipment, transducer amplifiers and radiation hard equipment.
