GENERAL DESCRIPTION
The OP777 , OP727 , and OP747 are precision single , dual,
and quad rail-to-rail output single- supply amplifiers featuring
micropower operation and rail-to-rail output ranges. These
amplifier sprovideimprovedperformanceovertheindustry -standard
OP07 with ± 15 V supplies , and offer the further advantage of true
single -supply operation down to 2.7 V , and smaller package
options than any other high-voltage precision bipolar amplifier.
Outputs are stable with capacitive loads of over 500 pF. Supply
current is less than 300 µA per amplifier at 5 V. 500 series resis-
tors protect the inputs, allowing input signal levels several volts above
the positive supply without phase reversal.
Applications for these amplifiers include both line-powered and
portable instrumentation, remote sensor signal conditioning, and
precision filters.
The OP777, OP727, and OP747 are specified over the extended
industrial (–40°C to +85°C) temperature range. The OP777,
single, is available in 8-lead MSOP and 8-lead SOIC packages.
The OP747, quad, is available in 14-lead TSSOP and narrow
14-lead SO packages.Surface-mountdevicesinTSSOPand MSOP
packages are available in tape and reel only.
The OP727, dual, is available in 8-lead TSSOP and 8-lead
SOIC packages. The OP727 8-lead SOIC pin configuration
differs from the standard 8-lead operational amplifier pinout.

NOTES
1Absolute maximum ratings apply at 25°C, unless otherwise noted.
2Stresses 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
conditions for extended periods may affect device reliability.
3θJA is specified for worst-case conditions, i.e., θJA is specified for device soldered in
circuit board for surface-mount packages.

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 OP777/OP727/OP747 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.
