OH Series hall effect ICs and Elements

Based on hall-effect principle, a hall effect IC is usually composed of a reverse protector, voltage regulator, Hall voltage generator, differential amplifier, Schmitt trigger and an open-collector output on a single silicon chip. Hall effect products are one kind of magnetic sensor ICs, which can convert the changeable magnetic field signal into a digital voltage output.
