RDC solution delivers robust performance
The AD2S1200 is a complete monolithic resolver-to-digital convertor for variable speed control applications that require additional power
A complete monolithic resolver-to-digital convertor (RDC), the AD2S1200 equips designers with a fast accurate (up to +/-11arc-min), fully integrated, RDC solution for variable speed control applications that require additional power. Automotive applications, such as power-assisted steering systems, and industrial applications where there are large temperature variations, such as glass manufacturing, require robust, resolver-to-digital conversion to ensure stability and precise positioning of mechanical movements in harsh temperature environments.
The convertor contains a 12bit resolution tracking resolver and an onboard programmable sinusoidal oscillator that provides sine wave excitation.
Other key features include a fault-detection circuit that detects any loss of resolver signals, out-of-range input signals, input signal mismatch, or loss of position tracking.
The chip communicates via a 12bit parallel port or three-wire serial interface.
The resolver also provides an incremental encoder emulation output with 1024 pulses per revolution with additional directional pulse, eliminating the need for external A and B directional decode logic.
The device operates from a single 5V supply, with a temperature range of -40 to +125C.
The AD2S1200 is available in a 44-lead LQFP package and is priced starting at $12.00 in 1000-piece quantities.
The part is in full production, with samples now available.
