ADIsim Design/Simulation Tools (5)

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.
ADIsimPower™ Voltage Regulator Design Tool
This expert design tool produces custom DC-DC converter designs in about a minute. The user enters 5 inputs and chooses to optimize for efficiency, PCB space, cost, or part count. Output is a complete schematic, BOM, efficiency plot, and performance summary. A PDF summary and a blank PCB is offered for each design to facilitate fast prototyping to verify the design.
Analog Bridge Wizard
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.

Voltage Reference Selection & Evaluation Wizard
Voltage Reference Wizard (downloadable)
This Wizard helps you select the most suitable voltage for a use with a data converter. Supply the Wizard with a given data converter; it will provide you with a number of suitable references plus the maximum DC error contributed to your overall system. Or enter the amount of DC error your system can tolerate and find out which of ADI’s reference and data converter pairs will meet your requirement.
