PRODUCT INFORMATION

HAL

Programmable Linear Hall-Effect Sensor

The HAL 880 complements the existing

Hall-effect sensor family HAL 8xy to the

lower end. It is designed to fulfil the require-

ments of today’s state-of-the-art applica-

tions for linear and angular measurements

that require programmability to compensate

system tolerances.

Due to its good drift performance and pro-

grammability, the sensor can easily replace

non-programmable, standard linear sensors

in a wide variety of applications. Due to its

programmability, it also offers the additional

advantage of compensation of system toler-

ances. This is mandatory for applications

like accelerator pedal sensing, current mea-

surement, bending light, or head light

adjustment.

The sensor provides a linear, ratiometric

analog output signal with implemented wire-

break detection working with pull-up or pull-

down resistor.

Major characteristics

like

magnetic-field

range, sensitivity, VOQ (output voltage at

zero magnetic field), and the temperature

coefficients can easily be adjusted to the

magnetic circuit (linear and quadratic) by

programming the non-volatile memory.

The HAL 880 is available in the very small

leaded package TO92UT.
