Product Details

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.
