HAL 855
Programmable Linear Hall-Effect Sensor with Arbitrary Output Characteristic
Release Note: Revision bars indicate significant changes to the previous edition.
Micronas. The sensors are designed for automotive or industrial applications. They operate with ambient temperatures from −40 °C up to 150 °C. The HAL855 is available in the very small leaded package TO92UT-1 and TO92UT-2.
1. Introduction
The HAL855 is a member of the Micronas family of programmable linear Hall sensors. As an extension to the HAL8x5 family, the HAL855 offers an arbitrary output characteristic and individual programming of different sensors which are in parallel to the s.
