The OP27 precision operational amplifier combines the low offset and drift of the OP07 with both high speed and low noise. Offsets down to 25µV and drift of 0.6µV/°C maximum make the OP27 ideal for precision instrumentation applications. Exceptionally low noise, a low 1/f noise corner frequency, 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/µsec slew rate provides excellent dynamic accuracy in high-speed data-acquisition systems. A low input bias current of ±10nA typical is achieved by use of a bias-current-cancellation circuit. The output stage has good load driving capability. A guaranteed swing of ±10V into 600 Ohms and low output distortion make the OP27 an excellent choice for audio applications. PSRR and CMRR exceed 120dB. These characteristics, coupled with long-term drift of 0.2µV/month, allow the circuit designer to achieve performance levels previously attained only by discrete designs.
