Resolver / Digital converters (Smartcoder)

Smartcoder is a R/D (Resolver to Digital) conversion IC, which converts resolver signals into digital absolute position angle signals.
It is usable in a wide range of applications, including vehicle/robot/machine tool related applications, in combination with brushless resolvers such as our Smartsyn and Singlsyn.
