Analog Devices AN-265 Application Note

About this manual

This application note discusses useful circuit applications for the AD2S80A and AD2S81A monolithic resolver-to-digital converters. It covers interfacing with high voltage synchros and resolvers, connecting to a 15V supply, and using the converters as control transformers. The document also explains how to use the converters with external pitch or revolution counters and how to simulate an incremental encoder.
