Figure 27 shows a suggested buffer circuit. Capacitor C1 may be
used in parallel with Resistor R2 to filter out any noise that may
exist on the EXC and EXC outputs. Care should be taken when
selecting the cutoff frequency of this filter to ensure that phase
shifts of the carrier caused by the filter do not exceed the phase
lock range of the AD2S1210.

where:
ω is the radian frequency of the applied signal.
VREF, a dc voltage, is set so that VOUT is always a positive value,
eliminating the need for a negative supply.

Figure 26. Connecting the AD2S1210 to a Resolver
In this recommended configuration, the converter introduces a
VREF/2 offset in the SIN, SINLO, COS, and COSLO signal outputs
from the resolver. The sine and cosine signals can each be
connected to a different potential relative to ground if the sine
and cosine signals adhere to the recommended specifications.
Note that because the EXC and EXC outputs are differential,
there is an inherent gain of 2×.
Figure 27. Buffer Circuit
A separate screened twisted pair cable is recommended for the
analog input pins, SIN, SINLO, COS, and COSLO. The screens
should terminate to either REFOUT or AGND.
