AD2S80AUD

可变分辨率，单片分解器数字转换器 Variable Resolution, Monolithic Resolver-to-Digital Converter

GENERAL DESCRIPTION

The AD2S80A is a monolithic 10-, 12-, 14-, or 16-bit tracking resolver-to-digital converter contained in a 40-lead DIP or 44-terminal 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 converter 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 be 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 AD2S80A 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.
