AD2S1210DSTZ (ANALOG DEVICES)

The AD2S1210DSTZ 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 3.15V p-p ±27% input signals on the sine and cosine inputs. A Type II tracking 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. A fault detection circuit can sense loss of resolver signals, out-of-range input signals, input signal mismatch or loss of position tracking. The fault detection threshold levels can be individually programmed by the user for optimization within a particular application.
