Overview
The AD2S82AJP is a variable resolution, monolithic resolver-to-digital converter produced by Analog Devices Inc. This device is part of the AD2S82A series and is packaged in a 44-lead plastic leaded chip carrier (PLCC) package. It offers high flexibility and performance, making it suitable for various industrial and automotive applications. The AD2S82AJP converts resolver format input signals into a parallel natural binary digital word using a ratiometric tracking conversion method, ensuring high noise immunity and tolerance of lead length when the converter is remote from the resolver.
