Linear Hall Sensor - GH149X Series
Product Overview
The GH149X series linear Hall effect sensors from GOCHIP ELECTRONICS TECHNOLOGY (Shanghai) CO., LTD. are designed for precise magnetic field detection. Featuring integrated resistance correction for accurate sensitivity and temperature compensation, these sensors offer full voltage range (Rail-to-Rail) output for enhanced signal efficiency and higher accuracy. They are suitable for a wide operating temperature range of -40 to +150 and are responsive to both positive and negative magnetic fields. The output voltage is proportional to the supply voltage and the magnetic field strength, with enhanced temperature stability and sensitivity provided by the new Hall circuit. These sensors are ideal for consumer and industrial electronics applications requiring accurate linear output.
