ADIsimOpAmp™
This tool will help with the selection, evaluation and troubleshooting of voltage feedback Op-Amps. It uses typical data to model the behavior of a selected amplifier. It allows a user to select an amplifier, configure a circuit, apply a signal and evaluate the performance. It is useful for checking an amplifier's spec's such as Bandwidth, Slew Rate, Input/Output Range, Gain Error, Load Current, Stability Issues and DC Errors in a given circuit. -
Analog Filter Wizard 2.0
The Analog Filter Wizard™ helps you design a low-pass, high-pass, band-pass or band-stop filter with actual op amps. It then simulates the filter’s performance with these op amps in real time. You can ask the tool to optimize for power, noise, or voltage range, and it will pick op amps and passive components appropriately. Or you can adjust the components manually yourself.
