May 16, 2007
The AS5140H from Austriamicrosystems, Unterpremstaetten, Austria, is a 10-bit magnetic rotary encoder with resolution of 0.35° and the ability to recognize 1024 positions/360° turn. Position readings are accessible with either a serial or PWM interface; 3 differently programmable incremental outputs are also available, one of which delivers a 3-phase commutation signal for brushless DC motors. Other features include user-specific zero programming, diagnostics for magnet positioning, the ability to recognize interruptions to the power supply, and a daisy chain mode.
