AD2S1210DSTZ Description

The AD2S1210DSTZ is a complete 10-bit to 16-bit resolution tracking resolver-to-digital converter, integrating an onboard programmable sinusoidal oscillator 

that provides sine wave excitation for resolvers. The converter accepts 3.15 V p-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.
