GENERAL DESCRIPTION

The AD2S1205 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 3.15 V p-p ± 27 input signals on the Sin and Cos inputs. A Type II tracking 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 maximum tracking rate is a function of the external clock frequency. The performance of the AD2S105 is specified across a frequency range of 8.192 MHz ± 25, allowing a maximum tracking rate of 1250 rps.
