The OP37EPZ is a precision high speed Operational Amplifier 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.
