 Design Tools
ADIsimOpAmp™ Evaluation Tool
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.
Opamp Range / Gain / Error Calculator
This tool calculates the error budget and verifies the range of an op amp based on your application. Changing default values such as operating temperature, topology, gain, and resistor tolerance creates an error budget for your application. The error is broken out as absolute error, resolution error, and drift/gain error. This tool also verifies that the input and output levels are within the range of the op amp selected.
