The AD2S1205YSTZ is a complete 12-bit resolution tracking Resolver-to-digital Converter that contains an on-board programmable sinusoidal oscillator providing 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. The maximum tracking rate is a function of the external clock frequency. The performance of the AD2S105 is specified across a frequency range of 8.192MHz±25%, allowing a maximum tracking rate of 1250rps. The Type II tracking loop provides continuous output position data without conversion delay. It also provides noise immunity and tolerance of harmonic distortion on the reference and input signals.
