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 ,andofferthefurtheradvantageoftrue

single -supply operation down to

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 Ω 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.
