OP37GPZ - Low Noise Precision Operational Amplifier

The OP37 provides the same high performance as the OP27, but the design is optimized for circuits with gains greater than five. This design change increases slew rate to 17V/µsec and gain-bandwidth product to 63MHz.

The OP37 provides the low offset and drift of the OP07 plus higher speed and lower noise. Offsets down to 25µV and drift of 0.6µV/°C maximum make the OP-37 ideal for precision instrumentation applications. Exceptionally low noise (en=3.5nV/Hz at 10Hz), a low 1/f noise corner frequency of 2.7Hz, and the high gain of 1.8 million, allow accurate high-gain amplification of low-level signals.

The low input bias current of ±10nA and offset current of 7nA are achieved by using a bias-current-cancellation circuit. Over the military temperature range this typically holds IB and IOS to ±20nA and 15nA respectively.

The output stage has good load driving capability. A guaranteed swing of ±10V into 600 Ohm and low output distortion make the OP37 an excellent choice for professional audio applications.
