The AD2S1200 is a complete 12-bit resolution tracking resolver-to-digital converter, integrating an on-board programmable sinusoidal oscillator that provides sine wave excitation for resolvers. An external 8.192 MHz crystal is required to provide precision time reference. This clock is internally divided to generate a 4.096 MHz clock to drive all the peripherals.
The converter accepts 3.6 V p-p ±10% input signals, in the range of 10 kHz to 20 kHz on the Sin and Cos inputs. A Type II servo loop is employed to track the inputs and convert the input Sin and Cos information into a digital representation of the input angle and velocity. The bandwidth of the converter is set internally to 1.7 kHz with an external 8.192 MHz crystal. The maximum tracking rate is 1,000 rps.
At least one model within this product family is in production and available for purchase. The product is appropriate for new designs but newer alternatives may exist.
