AD2S1200WSTZ

AD2S1200 is a complete 12bit resolution tracking resolver-to-digital converter, integrating an on-board programmable sinusoidal oscillator that provides sine wave excitation for resolvers. An external 8.192MHz crystal is required to provide a precision time reference. This clock is internally divided to generate a 4.096MHz clock to drive all the peripherals. Typical application includes electric power steering, electric vehicles, integrated starter generator/alternator, encoder emulation and automotive motion sensing and control.
