Low-cost 12-bit IC Resolver-to-Digital Converter Emulates Optical Encoder

Complete AD2S90 has absolute-angular-position serial binary and 1024-line incremental-encoder A quad B output formats

The AD2S90 is a 12-bit monolithic resolver-to-digital converter. A successor to the AD2S81—the first 12-bit monolithic R/D converter, introduced in these pages in 1987 (Analog Dialogue 21-1, pp. 23-24)—the AD2S90 is complete and requires no external components for operation. Read full article
