AH49E Linear Hall Effect Sensor IC (AH49E Hall Sensor)
The AH49E Linear Hall Effect Sensor is a magnetic field sensor that provides an analog voltage output proportional to the strength and polarity of the applied magnetic field. It operates using the Hall effect principle, where a voltage is generated when a magnetic field is applied perpendicular to current flow in the sensor.
The output voltage varies linearly with the magnetic field, making it suitable for precise measurement and control applications. It can detect both north and south magnetic poles and produces a ratiometric output based on supply voltage.
