AD2S1210-EP is a high performance variable resolution 10-bit to 16-bit R/D converter with a programmable sine oscillator.
The AD2S1210-EP is a complete monolithic resolver-to-digital converter that integrates an on-board programmable sinusoidal oscillator to provide sine wave excitation for resolvers. It accepts differential input signals in the range of 2 kHz to 20 kHz and converts them into a digital representation of input angle and velocity using a Type II servo loop. The device supports resolutions from 10 to 16 bits, selectable by the user, and provides both parallel and serial data ports for absolute position and velocity outputs.
