12-Bit R/D Converter with Reference Oscillator
The AD2S1200 is a complete 12-bit resolution tracking resolver-to-digital converter that integrates an on-board programmable sinusoidal oscillator to provide sine wave excitation for resolvers. It accepts differential Sin and Cos inputs in the range of 10 kHz to 20 kHz and converts them into digital representations of input angle and velocity using a Type II servo loop. An external 8.192 MHz crystal is required to provide a precision time reference for the internal clock generation.
