Operational Amplifiers (Op Amps)

Analog Devices high speed (> 50 MHz) current feedback op amps enable you to operate at higher speeds. Current feedback op amps traditionally have wider bandwidths and higher slew rates than voltage feedback amplifiers and feature constant bandwidth which is independent of gain. A current feedback op amp responds to an error current at its low-impedance negative input terminal, rather than an error voltage, and produces a corresponding output voltage.

When your design requires general purpose op amps, Analog Devices broad portfolio of high speed op amps, precision op amps, and instrumentation amplifiers deliver the unmatched performance and exceptional value that you’re looking for.

Analog Devices high speed , high output current (≥100 mA) op amps deliver high output current while driving low impedance loads with excellent linearity. Whether it's high output current, low input bias current, 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.

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.

High supply voltage op amps are used in systems that demand the widest dynamic range with the best signal-to-noise ratio. Engineers turn to Analog Devices for high voltage amplifiers that deliver industry-leading performance. Increasingly, new high voltage amplifiers also offer features to improve system performance, cost, and robustness while easing the complexity of system design. New features include integrated input overvoltage protection (OVP), on-chip electromagnetic interference (EMI) filtering, higher electrostatic discharge (ESD) immunity, and greater resistance to latch-up in both powered and unpowered operations.

Analog Devices JFET input op amps or FastFET™ high speed (>50 MHz) input op amps provide high input impedance and ultralow input bias currents for high speed applications. The majority of our FET input op amps feature wide supply ranges from +5 V to ±12 V or higher and feature rail-to-rail outputs enabling wide dynamic range.

Low input bias current op amps are required whenever the difference of currents or voltage is small and needs to be measured accurately. These op amps are used so that the signal is not loaded down by the input of the op amps. Low input bias current op amps are critical for interfacing sensors in applications from photodiodes, pH meters, or other electrometer related functions to downstream electronics. Analog Devices has many precision op amps that fit the definition and range of these applications.

Analog Devices’ portfolio of low noise (≤ 10nV/√Hz) op amps includes many amps with the lowest noise performance in the industry. These high speed, low distortion (1 nV or less) op amps enable better signal fidelity in the most demanding conditions, allowing system designers to achieve the lowest total system noise performance in applications with high source impedances. We feature a considerable variety of these amps with wide supply ranges and low power.

Analog Devices low power op amps offer a variety of benefits in many applications such as prolonging battery life, easing waste heat management in end equipment, reducing self heating to minimize thermally induced offset shift, and reducing total system power consumption and cost. Offering power efficient devices without compromising speed, noise, and precision has been a key focus on developing products at ADI.

Analog Devices’ broad range of precision amplifiers provides industry-leading support to designers in need of traditional trimmed and zero-drift amplifier technology. Our precision amplifier 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).

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.

The latest zero-drift amplifiers from Analog Devices combine both auto-zero and chopping techniques to continuously self-correct for dc errors over time and temperature. This enables the amplifiers to achieve <4 microvolts of input offset error and input drift error of >20 nanovolts per degree Celsius. By design, zero-drift amplifiers 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. The new ADA4523-1, LTC2065, and LTC2068 are appropriate for applications requiring current sensing of electronic loads, power supplies, and motor control and offset correction in composite amplifiers used in instrumentation. ADI’s zero-drift amplifier portfolio is an ideal choice for high performance projects and in products that are required to have a long lifecycle.
