ADI OP727ARZ

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 ±15 V supplies, and offer the further advantage of true single-supply operation down to 3.0 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 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.
