RATIOMETRIC, LINEAR HALL-EFFECT SENSOR ICS The UGN3503LT, UGN3503U, and UGN3503UA Hall-effect sensor ICs accurately track extremely small changes in magnetic flux density—changes generally too small to operate Hall-effect switches. For motion detectors, gear tooth sensors, and proximity detectors, they are magnetically driven mirrors of mechanical events. As sensitive monitors of ele...
