Product Summary

The AD2S81AJD is a monolithic 12-bit fixed resolution tracking resolver-to-digital converter packaged in a 28-lead DIP. The AD2S81AJD 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. The applications of the AD2S81AJD include: DC Brushless and AC Motor Control, Process Control, Numerical Control of Machine Tools, Robotics, Axis Control.
