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 operational amplifiers (op amps) are used in high performance data acquisition systems in instrumentation, telecommunication, laboratory, and medical systems. Analog Devices’ high speed op amp portfolio ranges from 50 MHz to GHz in speed while minimizing power consumption, and is 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 ADI. 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.

Precision Op Amps

Analog Devices’ broad range of precision operational amplifiers (op amps) provides industry-leading support to designers in need of traditional trimmed and zero-drift amplifier technology. Our precision op amp family helps preserve the accuracy of DC information in an incoming signal with low offset voltage (Vos < 1 mV) and low temperature drift characteristics (TCVos < 2 μV/°C).

Rail-to-Rail Op Amps

Analog Devices’ high speed (> 50 MHz) rail-to-rail operational amplifiers (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, low distortion, or rail to rail, no one sets more performance standards for next-generation designs than ADI.

Zero-Drift Op Amps

The latest zero-drift operational amplifiers (op amps) from Analog Devices combine both auto-zero and chopping techniques to continuously self-correct for DC errors over time and temperature. This enables the op amps to achieve <4 µV of input offset error and input drift error of <20 nV/°C. By design, zero-drift op amps have no 1/f voltage noise, nor do they suffer from long-term drift, making them ideal for low speed sensing. By reducing the drift and noise, these products decrease the need for constant system-level calibration. Additionally, very small LFCSP packages reduce board space, and on-chip electromagnetic interference filters speed development time by eliminating the need for collaboration circuitry. They accomplish all these features while controlling cost. ADI’s zero-drift op amp portfolio is an ideal choice for high performance projects and in products that are required to have a long lifecycle.
