September 6, 2000
The A3421xKA and A3422xKA Hall-effect, direction-detection
sensor ICs are a new generation of special-function devices that
E1 E2
are capable of sensing the direction of rotation of a ring magnet. These transducers provide separate digital outputs that provide information on
XX
magnet rotation speed, direction, and magnet pole count. These devices eliminate the major manufacturing hurdles encountered in fine-pitch
direction-detection applications, namely maintaining accurate mechani-
