GENERAL DESCRIPTION

The OP37 provides the same high performance as the OP27,

but the design is optimized for circuits with gains greater than

five. This design change increases slew rate to 17 V/ms and

gain-bandwidth product to 63 MHz.

The OP37 provides the low offset and drift of the OP07

plus higher speed and lower noise. Offsets down to 25 mV and

a maximum drift of 0.6 mV/∞C make the OP37 ideal for preci-

sion instrumentation applications. Exceptionally low noise

2.7 Hz, and the high gain of 1.8 million, allow accurate

high-gain amplification of low-level signals.

The low input bias current of 10 nA and offset current of 7 nA

are achieved by using a bias-current cancellation circuit. Over

the military temperature range this typically holds I

to 20 nA and 15 nA respectively.

Operational Amplifier (A

The output stage has good load driving capability. A guaranteed

swing of 10 V into 600 W and low output distortion make the

OP37 an excellent choice for professional audio applications.

PSRR and CMRR exceed 120 dB. These characteristics, coupled

with long-term drift of 0.2 mV/month, allow the circuit designer

to achieve performance levels previously attained only by

discrete designs.

Low-cost, high-volume production of the OP37 is achieved by

using on-chip zener-zap trimming. This reliable and stable offset

trimming scheme has proved its effectiveness over many years of

production history.

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.
