Synchro/Resolver to Digital Converters

Resolvers and synchros are transducers that convert the angular position and/or velocity of a rotating shaft to an electrical signal. Both deliver signals proportional to the sine and/or cosine of the shaft angle. A resolver-to-digital or synchro-to-digital converter converts these signals to a digital output corresponding to the shaft angle and/or velocity. ADI’s family of RDCs and SDCs offer solutions for these applications.
