Programmable linear Hall Sensors HAL 880

The HAL 880 is designed to fulfil the requirements of
today‘s state-of-the-art applications for linear and angular
measurements that require flexibility to compensate system tolerances.
Due to its programmability, it also offers the additional
advantage of compensation of system tolerances. This is mandatory
for applications like accelerator pedal sensing, current
measurement, bending light or head light adjustment.
The sensor provides a linear, ratiometric analog output signal
with implemented wirebreak 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 a very small leaded package
TO92UT.
