Linear Hall-Effect Sensor with LIN Bus

The HAL 2810 is a member of the Micronas family HAL 28xy of programmable linear Hall-effect sensors.

It features a Hall-plate with spinning current offset compensation technique and a precise temperature sensor which is used for temperature compensation of both the Hall sensors sensitivity and offset.

特性 Features
