AD2S83AP Datasheet

Analog to Digital Converters - ADC


The AD2S83AP is a monolithic 10-, 12-, 14- or 16-bit trackingresolver-to-digital converter.The converter allows users to select their own resolution and dy-namic performance with external components. The converter allowsusers to select the resolution to be 10, 12, 14 or 16 bits and totrack resolver signals rotating at up to 1040 revs per second(62,400 rpm) when set to 10-bit resolution.The AD2S83AP converts resolver format input signals into a paral-lel natural binary digital word using a ratiometric tracking con-version method. This ensures high noise immunity and tolerance oflong leads allowing the converter to be located remote from theresolver.The position output from the converter is presented via 3-stateoutput pins which can be configured for operations with 8- or16-bit bus. BYTE SELECT,ENABLE and INHIBIT pinsensure easy data transfer to 8- and 16-bit data bus, and outputsare provided to allow for cycle or pitch counting in externalcounters.A precise analog signal proportional to velocity is also availableand will replace a tachogenerator.
