These amplifier s provide improved performance over the industry -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 p F. Supply current is less than 300 µA per amplifier at 5 V. 500 Ω series resistors 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-mount devices in TSSOP...
