UNISONIC TECHNOLOGIES CO., LTD Preliminary LINEAR INTEGRATED CIRCUIT DYNAMIC DIFFERENTIAL HALL EFFECT SENSOR IC WITH DIGITAL SIGNAL OUTPUT - DESCRIPTION The differential Hall Effect sensor UTC UH4921 provides a superior stability and a high sensitivity over temperature and symmetrical thresholds in order to achieve a stable duty cycle. The integrated circuit provides a digital signal output with frequency proportional to the speed of rotation. Unlike other rotational sensors differential Hall ICs are not influenced by radial vibration within the effective airgap of the sensor and require no external signal processing. UTC UH4921 is particularly suitable for rotational speed...
