Overview
The AD2S82AHP-REEL, produced by Analog Devices Inc., is a variable resolution, monolithic resolver-to-digital converter. This device is designed to convert 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, making it suitable for applications where the converter is remote from the resolver. The AD2S82AHP-REEL is available in a 44-lead J-leaded PLCC package and supports resolutions of 10, 12, 14, or 16 bits.
