AD2S82AHP

Product Summary

The AD2S82AHP 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 AD2S82AHP converter allows 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 AD2S82AHP 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 AD2S82AHP 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. The applicaitons of the device include DC Brushless and AC Motor Control, Process Control, Numerical Control of Machine Tools, Robotics and Axis Control.
