Micronas GmbH has announced the availability of what it claims to be the world's first programmable hall sensor that is able to linearize magnetic fields measured by the sensor element.

The HAL 855 is claimed to have enough on-chip EEPROM to store the typical output characteristics of an application such as fuel indication, while on-chip DSP circuitry performs the computation required to digitize the magnetic field and translates it according to the data stored in the EEPROM into the nonlinear output data and vice versa.

Designed to replace various conventional potentiometers, the hall sensor can also be used for the detection of position and angles in vehicles and industrial applications.

The HAL 855 operates over the -400C to 1500C temperature range and is priced at $1.50 each in high-volume quantities.
