Operational Amplifiers

Operational Amplifiers

The operational amplifier (op amp) is an important part of any analog signal chain, often working as a crucial part of the interface between sensors and our world-leading ADCs. Common analog op amp functions include gain, buffering, filtering, and level-shifting. Analog Devices’ portfolio provides the broadest choice of op amps in the industry, delivering unmatched quality, robustness, and performance to enable optimized solutions in automotive, industrial, consumer, and healthcare markets. Explore op amps by parameters and find expert system-level advice on design problems with our reference designs (Circuits from the Lab®), design tools, selection guides, filter design, calculators, and LTSpice®/SPICE models for operational amplifiers.

High Speed Op Amps

High Speed Op Amps are used in high performance data acquisition systems in instrumentation, telecommunication, laboratory, and medical systems. Analog Devices high speed operational amplifier portfolio ranges from 50MHz to GHz in speed while minimizing power consumption, and are the number one selling brand of high speed amps in the world today. Whether it's wide bandwidth, high slew rate, or low distortion, no one sets more performance standards for next generation designs, with the widest portfolio of leading edge products, than Analog Devices. Designers who want dependable, reliable parts that enable the highest performance from their design come here for the ultimate source in high speed op amps.

Rail-to-Rail Op Amps

Analog Devices high speed (> 50 MHz) rail-to-rail op amps enable you to operate at lower supply voltages, swing closer to the rails, and provide wider dynamic range. Featuring a portfolio with a wide variety of op amps, including both rail-to-rail input/output as well as just rail-to-rail output, ADI provides the widest portfolio of leading edge products available on the market. Whether it is wide bandwidth, high slew rate or low distortion, or rail to rail, no one sets more performance standards for next generation designs than Analog Devices.

Analog Filter Wizard Design Tool

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.
