Product Details
The OP747 a precision quad rail-to-rail output single-supply amplifier featuring micropower operation and rail-to-rail output ranges. The OP777, OP727, and OP747 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 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 abovethe 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.

Design Tools
Analog Filter Wizard
Use the Analog Filter Wizard to design low-pass, high-pass, or band-pass filters with actual op amps in minutes. As you progress through the design process, you can observe the characteristics of your filter design from ideal specifications to real world circuit behavior. Quickly evaluate the tradeoffs in op amp specifications - including gain-bandwidth, noise, and supply current – to determine the best filter design for your requirements.
Analog Photodiode Wizard
Use Photodiode Wizard to design a transimpedance amplifier circuit to interface with a photodiode. Select a photodiode from the library included in the tool, or enter custom photodiode specifications. Quickly observe tradeoffs between Bandwidth, Peaking (Q), and ENOB/SNR. Modify circuit parameters, and immediately see results in plots for pulse response, frequency response, and noise gain.
