Tel: 781/329-4700 www.analog.com Fax: 781/326-8703 © Analog Devices, Inc., 2001 FEATURES Low Offset Voltage: 100 V Max Low Input Bias Current: 10 nA Max Single-Supply Operation: 2.7 V to 30 V Dual-Supply Operation: 1.35 V to 15 V Low Supply Current: 300 A/Amp Max Unity Gain Stable No Phase Reversal APPLICATIONS Current Sensing (Shunt) Line or Battery-Powered Instrumentation Remote Sensors Precision Filters OP727 SOIC Pin-Compatible with LT1013 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 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 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.
