GENERAL DESCRIPTION
The OP-27 precision operational amplifier combines the low
offset and drift of the OP-O7 with both high speed and low
noise. Offsets down to 25p1/ and drift of 0.6pV/" C maximum
make the OP-27 ideal for precision instrumentation applica-
signals. A gain-bandwidth product of 8MHz and a 2.8V/pSec
slew rate provides excellent dynamic accuracy in high-speed
data-acquisition systems.
A low input bias current of t10nA is achieved by use of a
bias-current-cancellation circiiit. Over the military temper-
ature range, this circuit typically holds les and los to i20nA
and 15nA respectively.
The output stage has good load driving capability. A guaran-
teed swing ofi10V into 6000 and low outputdistortion make
the OP-27 an excellent choice for professional audio applica-
tions.
PSRR and CMRR exceed 120dB. These ttharattteristitts,
coupled with Iong-term drift of0.2pV/month,allowthecirduit
designer to achieve performance levels previously attained
only by discrete designs.

Low cost, high-volume production of OP-27 is achieved by
using an on-chip zener-zap trimming network. This reliable
and stable offset trimming scheme has proved its effective-
ness over many years of production history.
The OP-27 provides excellent performance in Iow-noise
high-accuracy amplification of low-level signals. Applica-
tions include stable integrators, precision summing ampli-
tiers, precision voltage-threshold detectors, comparators.
and professional audio circuits such as tape-head and
microphone preamplifiers.
The OP-27 is a direct replacement for725, OP-06, OP-07 and
OP-05 amplifiers; 741 types may be directly replaced by
removing the 741's nulling potentiometer.

NOTES:
1. For supply voltages less than 122V, the absolute maximum input voltage is
equal to the supply voltage.
2. The OP-27's inputs are protected by battk-ttFbatht diodes. Current limiting
resistors ate not used in order to achieve low noise. "differential inputvoltage
exceeds 10.7V, the input current should be limited m 25mA.
3. IV is specified for worst case mounting conditions. i.e.. ' is specified for
device in socket for TO, CerDIP. P-DIP, and LCC packages; SM is specitied
for device soldered to printed circuit board for so package.
4. Absolute maximum ratings apply to both DICE and packaged parts, unless
otherwise noted.
