Hall sensor can be divided into linear Hall transmission element and switching Hall element.
(1) Switch Hall element is composed of voltage regulator, Hall element, differential amplifier, Schmitt trigger and output stage, which outputs digital quantity. There is also a special type of on-off Hall sensor, called lock key Hall sensor.
(2) The linear Hall element consists of a Hall element, a linear amplifier and an emitter follower, and outputs analog signals. Linear Hall sensors can be divided into open-loop and closed-loop types. Closed-loop Hall sensor is also called zero-flux Hall sensor.
Linear Hall sensor is mainly used to measure AC /DC current and voltage. Therefore, when choosing the Hall switch, we must first make clear the type of switch we need and the specific parameters we need.
