AD2S1210 is a complete monolithic resolver-to-digital converter from Analog Devices with a variable resolution of 10 bits to 16 bits and a reference oscillator. The converter is an integrated harmonic demodulator that can demodulate AC and DC servo motors with a single device.
The AD2S1210 from Analog Devices converts resolver signals to digital position and velocity data with selectable 10‑ to 16‑bit resolution. It integrates a programmable sinusoidal oscillator for excitation and provides both parallel and serial data ports, as well as incremental encoder emulation.
The device includes programmable fault‑detection thresholds, operates from a 5 V supply, and is rated for industrial temperature ranges up to +125 °C. Detailed specifications, timing parameters, and register maps are provided for system designers.
