AD2S99/AD2S82A TYPICAL CONFIGURATION
Figure 4 shows a typical circuit configuration for the AD2S99
Oscillator and the AD2S82A Resolver-to-Digital Converter.
The maximum level of the SIN and COS input signals to the
AD2S82A should be 2 V rms 10%. All the analog ground sig-
nals should be star connected to the AD2S82A AGND pin. If
shielded twisted pair cables are used for the resolver signals, the
shields should also be terminated at the AD2S82A AGND pin.

Coupling capacitor C3, and resistor to GND R3, between the
SYNREF output of the AD2S99 and the REF input pin of the
AD2S82A are optional. For additional information on selecting
component values for the AD2S82A, please refer to the
AD2S82A data sheet or the application note “Passive Compo-
nent Selection and Dynamic Modeling for the AD2S80 Series
Resolver-to-Digital Converters” (AN-266).
