Data Sheet OP27
GENERAL DESCRIPTION
(Continued from Page 1) The OP27 provides excellent performance in low noise, PSRR and CMRR exceed 120 dB. These characteristics, coupled high accuracy amplification of low level signals. Applications with long-term drift of 0.2 µV/month, allow the circuit designer include stable integrators, precision summing amplifiers, to achieve performance levels previously attained only by discrete precision voltage threshold detectors, comparators, and designs. professional audio circuits such as tape heads and microphone preamplifiers. Low cost, high volume production of OP27 is achieved by using an on-chip Zener zap-trimming network. This reliable and stable offset trimming scheme has proven its effectiveness over many years of production history. Rev. H | Page 3 of 21
