GENERAL DESCRIPTION
The AD2S1210 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 3.15 V p-p ± 27% input signals, in the range
of 2 kHz to 20 kHz on the sine and cosine inputs. A Type II
servo 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 3125 rps
