A1351 High Precision Linear Hall Effect Sensor IC

TheA1351 device is a high precision, programmable linear Hall effect sensor IC with a pulse width modulated (PWM) output. The duty cycle, D, of the PWM output signal is proportional to an applied magnetic field. The A1351 device converts an analog signal from its internal Hall element to a digitally.
