AD2S80ATD

Product Summary

The AD2S80ATD is a monolithic 10-, 12-, 14- or 16-bit tracking resolver-to-digital converter contained in a 40-pin DIP or 44-pin LCC ceramic package. It is manufactured on a BiMOS II process that combines the advantages of CMOS logic and bipolar high accuracy linear circuits on the same chip. The AD2S80ATD allows users to select their own resolution and dynamic performance with external components. This allows the users great flexibility in defining the converter that best suits their system requirements. The converter allows users to select the resolution to he 10, 12, 14 or 16 bits and to track resolver signals rotating at up to 1040 revs per second(62,400 rpm) when set to 10-bit resolution. The AD2S80ATD converts resolver format input signals into a parallel natural binary digital word using a ratiometric tracking conversion method. This ensures high-noise immunity and tolerance of lead length when the converter is remote from the resolver.
