ADI AD2S1210WDSTZRL7

The AD2S1210 is a complete 10- bit to 16- bit resolution tracking resolver- to- digital converter; integrating an on- board programmable sinusoidal oscillator that provides sine wave excitation for resolvers. The converter accepts 3.15 V p ± 27% input signals, in the range of 2 kHz to 20 kHz on the sine and cosine inputs. A Type II servo loop is employed to track the inputs and convert the input sine and cosine information into a digital representation of the input angle and velocity. The maximum tracking rate is 3125 rps.
