ADI OP747ARUZ-REEL

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 amplifiers provide improved performance over the industry-standard OP07 with ±15V supplies, and offer the further advantage of true single-supply operation down to 3.0V, and smaller package options than any other high-voltage precision bipolar amplifier. Outputs are stable with capacitive loads of over 500pF. Supply current is less than 300μA per amplifier at 5V. 500Ω 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 and 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.
