Product Overview

The GH1922U is a high-precision differential Hall effect sensor IC designed for detecting changes in magnetic fields. It utilizes a differential Hall sensor structure to minimize the impact of temperature drift, manufacturing variations, and bias magnetic field fluctuations. This makes it ideal for non-zero speed detection applications, including gear and position sensing. The device operates reliably within a wide voltage (3.5-24V) and temperature (-40 to +150) range, offering features like high sensitivity, wide detection distance, stable duty cycle, and immunity to physical stress and EMI.
