Analog Devices AN-266 Passive Component Selection and Dynamic Modeling for the 2S80 Series Resolver-to-Digital Converter
Analog Devices presents a software package designed to simplify the computation of external passive component values required for the 2S80 Series Resolver-to-Digital Converters. The application allows users to specify reference frequency, digital resolution, and tracking bandwidth to calculate optimal resistor and capacitor settings.
The software provides graphical displays of the closed-loop transfer function (gain and phase) and small-signal step responses. Users can adjust component values interactively to observe changes in converter dynamics, ensuring proper configuration for specific application requirements.
