1 3421 AND 3422 PRELIMINARY INFORMATION HALL-EFFECT, (subject to change without notice) DIRECTION-DETECTION SENSOR ICS 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- SUPPLY DIRECTION GROUND E1 OUTPUT SPEED LOGI...
