Stumbled upon this incredibly useful filter wizard from Analog Devices and thought surely someone else will want to know about this online tool – the circuit diagram and bill of materials export are also useful features!

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.
