Operational Amplifiers (Op Amps)
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.

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.
