GENERAL DESCRIPTIONThe OP777 is a precision single supply amplifier featuring
micropower operation and rail-to-rail output ranges. This ampli-
fier provides improved performance over the industry-standard
OP07 with ±15 V supplies and offers the further advantage of
true single supply operation down to 2.7 V, and smaller package
footprint than any other high-voltage precision bipolar amplifier.
Outputs are stable with capacitive loads of over 1000 pF. Supply
current is less than 300 µA per amplifier at 5 V. 500 Ω series resis-
tors protect the inputs, allowing input signal levels to exceed either
power supply rail by up to 3 V without causing phase reversal of the
output signal or causing damage to the amplifier. The proprietary
fabrication process yields a very low-voltage noise corner frequency
under 10 Hz, greatly improving the low-frequency noise perfor-
mance of the OP07 and similar amplifiers. The specially fabricated
input PNP transistors operate with very low input bias currents while
allowing operation with large differential voltages, eliminating a
common limitation of many precision amplifiers and enabling
application of the OP777 in precision comparator and rectifier
circuits. This large differential voltage capability also further reduces
the need for external protection devices such as clamping diodes.
Applications for these amplifiers include both line powered and
portable instrumentation, remote sensor signal conditioning, and
precision filters.
The OP777 is specified over the extended industrial (–40°C to
+85°C) temperature range and is available in 8-lead MSOP and
8-lead SOIC packages. The OP777 uses a standard operational
amplifier pinout, allowing for easy drop-in replacement of lower
performance amplifiers in most circuits. Surface mount devices
in MSOP packages are available in tape and reel only.

*Stresses above those listed under Absolute Maximum Ratings may cause perma-
nent damage to the device. This is a stress rating only; functional operation of the
device at these or any other conditions above those listed in the operational sections
of this specification is not implied. Exposure to absolute maximum rating condi-
tions for extended periods may affect device reliability.
NOTEθJA is specified for worst-case conditions, i.e., θJA is specified for device soldered
in circuit board for surface-mount packages.
CAUTIONESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000V readily
accumulate on the human body and test equipment and can discharge without detection. Although
the OP777 features proprietary ESD protection circuitry, permanent damage may occur on devices
subjected to high-energy electrostatic discharges. Therefore, proper ESD precautions are recom-
mended to avoid performance degradation or loss of functionality.
