Analog Devices OP37GS
the OP37 an excellent choice for professional audio applications. These characteristics, coupled with long-term drift of 0.2 µV/month, allow the circuit designer to achieve performance levels previously attained only by discrete designs. This reliable and stable offset trimming scheme has proved its effectiveness over many years of production history.FEATURES

GENERAL DESCRIPTION
Low Noise, Precision, High Speed Operational Amplifier (A VCL > 5) OP37 The output stage has good load driving capability. A guaranteed swing of 10 V into 600 Ω and low output distortion make PSRR and CMRR exceed 120 dB. Low-cost, high-volume production of the OP37 is achieved by using on-chip zener-zap trimming. The OP37 brings low-noise instrumentation-type performance to such diverse applications as microphone, tapehead, and RIAA phono preamplifiers, high-speed signal conditioning for data acquisition systems, and wide-bandwidth instrumentation.
