Product Summary

The AD2S80ALD 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 AD2S80ALD 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 applications of the AD2S80ALD include: DC Brushless and AC Motor Control, Process Control, Numerical Control of Machine Tools, Robotics, Axis Control, Military Servo Control.
