GENERAL DESCRIPTION
The OP-37 provides the same high performance as the OP-27,
but the design is optimized for circuits with gains greater
than five. This design change increases slew rate to 17V/psec
and gain-bandwidth product to 63MHz.
SIMPLIFIED SCHEMATIC
The OP-37 provides the low offset and drift of the OP-07 plus
higherspeed and lower noise. Offsets down to 25pV and drift
of 0.6uV/°C maximum make the OP-37 ideal for precision
instrumentation applications. Exceptionally low noise
(en=3.5nV/\/ Hz at10Hz),alow1/fnoisecornerfrequencyof
2.7Hz, and thehigh gain of1.8 million,allowaccurate high-gain
amplification of low-level signals.
The Iowinputbiastrurrentott10nAand offsetcurrent of7nAare
achieved by using a bias-currentkancellation circuit. Over
the military temperature range this typically holds lgand log
to :20nA and 15nA respectively.
The output stage has good load driving capability. Aguaran-
teed swing ofi1OV into 600n and low output distortion make
the OP-37 an excellent choice for professional audio
applications.

PSRR and CMRR exceed 120dB. These characteristics,
coupled with long-term drift ofth2pV/month, allow the circuit
designer to achieve performance levels previously attained
only by discrete designs.
Low-cost, high-volume production of the OP-37 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 OP-37 brings low-noise instrumentation-type perfor-
mance to such diverse applications as microphone, tape-
head, and RIAA phono preamplifiers, high-speed signal con-
ditioning for data acquisition systems, and wide-bandwidth
instrumentation.

NOTES:
1. For supply voltages less than s22V, the absolute maximum input voltage is
equal to the supply voltage.
2. The OP-37's inputs are protected by back-to-back diodes. Current limiting
resistors are not used in orderto achieve low noise. If differential inputvoltage
exceeds :0.7V, the input current should be limited to 25mA.
3. IV is specified for worst case mounting conditions. ie., e A is specified for
device in socket for TO, CerDlP. P-DIP, and LCC packages; N is specified
for device soldered to printed circuit board for 80 package.
4. Absolute maximum ratings apply to both DICE and packaged parts, unless
otherwise noted.
