Low-Noise, Precision Operational Amplifier
The OP27 precision operational amplifier combines the low offset and drift of the OP07 with both high speed and low noise. Offsets down to 25mV and maximum drift of 0.6mV/°C, makes the OP27 ideal for precision instrumentation applications. Exceptionally low noise, en = 3.5nV/vHz, at 10Hz, a low 1/f noise corner frequency of 2.7Hz, and high gain (1.8 million), allow accurate high-gain amplification of low-level signals. A gain-bandwidth product of 8MHz and a 2.8V/ms slew rate provides excellent dynamic accuracy in high-speed, dataacquisition systems. A low input bias current of +/-10nA is achieved by use of a bias-current-cancellation circuit. Over the military temperature range, this circuit typically holds IB and IOS to +/-20nA and 15nA, respectively. The output stage has good load driving capability. A guaranteed swing of +/-10V into 600W and low output distortion make the OP27 an excellent choice for professional audio applications.
