AD2S83:  Variable Resolution Resolver-to-Digital Converter

Product Details


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.

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.
