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
(en= 3.5 nV/ @ 10 Hz), a low 1/f noise corner frequency of
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 IB and IOS
to 20 nA and 15 nA respectively.

OP37
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.
