3121 HALL-EFFECT SWITCHES FOR HIGH-TEMPERATURE OPERATION

3121, 3122, AND 3123 HALL-EFFECT SWITCHES FOR HIGH-TEMPERATURE OPERATION These Hall-effect switches are monolithic integrated circuits with tighter magnetic specifications, designed to operate continuously over extended temperatures to +150°C, and are more stable with both temperature and supply voltage changes. The unipolar switching characteristic makes these devices ideal for use with a simple bar or rod magnet. The three basic devices (3121, 3122, and 3123) are identical except for magnetic.
