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.
The AD2S1210WDSTZ and the AD2S1210WDSTZRL7 models have been approved by an independent accredited body for use in Automotive Safety Integrity Level B rated applications according to ISO 26262.
