Product Summary

The AD2S82ALP 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 package–COMPLEMENT and VCO output. The AD2S82ALP 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 AD2S82ALP 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 lead length when the converter is remote from the resolver.
