AD2S81A General Description
The AD2S82A is a monolithic 10-, 12-, 14- or 16-bit tracking resolver-to-digital converter contained in a 44-lead J leaded PLCC package. Two extra functions are provided in the new surface mount packageCOMPLEMENT and VCO output.
The AD2S81A is a monolithic 12-bit fixed resolution tracking resolver-to-digital converter packaged in a 28-lead DIP.
The converters allow users to select their own dynamic performance with external components. This allows the users great flexibility in defining the converter that best suits their system requirements.
The AD2S82A allows users to select the resolution to be 10, 12, 14 or 16 bits and to track resolver signals rotating at up to 1040 revs per second (62,400 rpm) when set to 10-bit resolution.
The AD2S81A and AD2S82A convert 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 lead length when the converter is remote from the resolver.
