AD2S99/AD2S93 TYPICAL CONFIGURATION
Figure 5 shows a typical circuit configuration for the AD2S99
Oscillator and the AD2S93 LVDT-to-Digital Converter. The
maximum level of the A and B transducer input signals to the
AD2S93 should be 1 V rms
± 20%. All the analog ground sig-
nals should be star connected to the AD2S93 AGND pin. If
shielded twisted pair cables are used for the LVDT signals, the
shields should also be terminated at the AD2S93 AGND pin.
The SYNREF output of the AD2S99 cannot be used as the
REF input signal for the AD2S93. The zero crossing reference
for the AD2S93 should be taken from the primary winding of
the LVDT through a phase lead or lag network. The phase com-
pensation network ensures that the REF input is phase coherent
with the A and B input signals to the AD2S93.
