GENERAL DESCRIPTION

The AD2S83 is a monolithic 10-, 12-, 14-, or 16-bit tracking resolver-to-digital converter.

The converter allows users to select their own resolution and dynamic performance with external components. The converter 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 AD2S83 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 position output from the converter is presented via 3-state output pins which can be configured for operations with 8- or 16-bit bus. BYTE SELECT, ENABLE and INHIBIT pins ensure easy data transfer to 8- and 16-bit data bus, and outputs are provided to allow for cycle or pitch counting in external counters.

A precise analog signal proportional to velocity is also available and will replace a tachogenerator.

The AD2S83 operates over reference frequencies in the range 0 Hz to 20,000 Hz.
