GENERAL DESCRIPTION
The AD2S93 is a complete 14-bit resolution tracking LVDT-to digital converter. A Type II tracking loop is employed to track the A–B input and produce a digital output equal to (A–B)/ (REF/2), where REF is a fixed amplitude ac reference phase coherent with the A–B input. This allows the measurement of any 2-, 3-, 4- and 5-wire LVDT or linear amplitude modulated in put. The operating frequency range is from 360 Hz to 10 kHz with user definable bandwidth set externally within a range of 45 Hz to 1250 Hz.
