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.
Full details about this enhanced product, including theory of operation, registers details, and applications information, are available in the AD2S1210 data sheet, which should be concluded in conjunction with this data sheet.
