Description

The OP37 provides the same high performance as the OP-27, 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 OP37 ideal for precision instrumentation applications. Exceptionally low noise, a low 1/f noise corner frequency , 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.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 audio applications.
