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
