The document is an application note (AN-230) from Analog Devices regarding the AD2S90 Resolver-to-Digital Converter. It details specific circuit implementations for digitizing resolver signals without external components.
The text covers three main applications: absolute position data serial-to-parallel conversion using shift registers, EIA-485 communication for long-distance data transmission, and 4096 line incremental encoder emulation.
The maximum serial clock rate could be as high as 2 MHz with a 50% duty cycle.
The device provides a 12-bit resolution.
Yes, it can emulate a 4096 line incremental encoder by multiplying the 1024 line count by 4.
