AD2S99/AD2S90 TYPICAL CONFIGURATION

shields should also be terminated at the AD2S90 AGND pin.

The SYNREF output of the AD2S99 should be connected to

the REF input pin of the AD2S90 via a 0.1 µF capacitor with a

100 kΩ resistor to GND. This is to block out any dc offset in

the SYNREF signal. For more detailed information please refer

to the AD2S90 data sheet.

Figure 3 shows a typical circuit configuration for the AD2S99

Oscillator and the AD2S90 Resolver-to-Digital Converter. The

maximum level of the SIN and COS input signals to the

AD2S90 should be 2 V rms ±10%. All the analog ground sig-

nals should be star connected to the AD2S90 AGND pin. If

shielded twisted pair cables are used for the resolver signals, the
