Data Sheets for the AD2S81A and the AD2S82A are available under "More Data Sheets".

The AD2S80A/AD2S81A/AD2S82A series are monolithic 10-, 12-, 14, or 16-bit tracking resolver-to-digital converters.

The converter allows users to select their own resolution and dynamic performance with external components. This allows the users great flexibility in defining the converter that best suits their system requirements. The converter allows users to select the resolution to be 10, 12, 14, or 16 bits [AD2S81A allows 12 bit resolution only] and to track resolver signals rotating at up to 1040 revs per second (62,400 rpm) when set to 10-bit resolution.

The AD2S80A/AD2S81A/AD2S82A series converts resolver format input signals into a parallel natural binary digital word using a ratiometric tracking conversion method. This ensures high noise immunity and tolerance of long leads allowing the converter to be located remote from the resolver.

The AD2S80A/AD2S81A/AD2S82A series operates over reference frequencies in the range 50 Hz to 20,000 Hz.
