OP27
(Continued from page 1)
PSRR and CMRR exceed 120 dB. These characteristics, coupled
with long-term drift of 0.2
µV/month,
allow the circuit designer
to achieve performance levels previously attained only by dis-
crete designs.
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 proved its effectiveness
over many years of production history.
The OP27 provides excellent performance in low-noise, high-
accuracy amplification of low-level signals. Applications include
stable integrators, precision summing amplifiers, precision voltage-
threshold detectors, comparators, and professional audio circuits
such as tape-head and microphone preamplifiers.
The OP27 is a direct replacement for 725, OP06, OP07, and
OP45 amplifiers; 741 types may be directly replaced by remov-
ing the 741’s nulling potentiometer.

NOTES
1
For supply voltages less than
±
22 V, the absolute maximum input voltage is
equal to the supply voltage.
2
The OP27’s inputs are protected by back-to-back diodes. Current limiting
resistors are not used in order to achieve low noise. If differential input voltage
exceeds
±
0.7 V, the input current should be limited to 25 mA.

JA
is specified for worst-case mounting conditions, i.e.,
JA
is specified for
device in socket for TO, CERDIP, and P-DIP packages;
JA
is specified for
device soldered to printed circuit board for SO package.

Absolute Maximum Ratings apply to both DICE and packaged parts, unless
otherwise noted.

CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily
accumulate on the human body and test equipment and can discharge without detection. Although
the OP27 features proprietary ESD protection circuitry, permanent damage may occur on devices
subjected to high-energy electrostatic discharges. Therefore, proper ESD precautions are
recommended to avoid performance degradation or loss of functionality.
