Overview
The AD2S82AHPZ, produced by Analog Devices Inc., is a monolithic variable resolution tracking resolver-to-digital converter. This device is packaged in a 44-lead J-leaded PLCC (Plastic Leaded Chip Carrier) package. It offers the flexibility of selecting resolutions of 10, 12, 14, or 16 bits, making it highly versatile for various applications. The converter uses a ratiometric tracking conversion method, ensuring high noise immunity and tolerance to lead length variations, which is particularly beneficial when the converter is remote from the resolver.
