Analog Devices AN-265 Application Note
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.

Questions answered in these manuals
What is the maximum tracking rate for the AD2S81A?
The converter can track signals at rates up to 260 revolutions per second.
What is the accuracy of the AD2S80A?
The device offers accuracy up to 2 arc mins plus 1 LSB.
What is the function of the AD2S80A in this application?
The ratio multiplier section of the AD2S80A is used independently to perform the function of a control transformer.
What is the purpose of the high frequency filter?
It is used to remove any DC offset from the AC error output and to attenuate any high frequency noise induced to the converter.
What resolution options does the AD2S80A support?
The converter can be set to 10, 12, 14, or 16‑bit resolution by the user.
