2.2 Resolver Interface Pinout

The AMC1210MB-EVM is designed for easy interfacing to resolver applications. Connector J5 is a

nine-pin, female-type DSUB connector for connection to a standard resolver. To hold the floating resolver

inputs to a predefined common-mode level, a 2.5-V offset is added to the resolver inputs. The

AMC1210MB-EVM resolver interface pinout is detailed in Table 2.
