The OP37GJ 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 OP37GJ 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 OP37GJ an excellent choice for professional audio applications.
