Abstract
This article introduces the working principle,main features,technical specifications,and calculation method of peripheral component parameters for the AD2S80A rotary variable digital converter(RDC).Through this method,we calculated the peripheral resistance and capacitance matching values for AD2S80A applicable to multi-pole dual-channel rotary transformers at frequencies of 400 Hz,1 000 Hz,and 2 000 Hz.This article uses comparative graphs to illustrate the curve comparisons of results after applying this calculation method,emphasizing the importance of peripheral component parameter configuration for the conversion accuracy of AD2S80A.
