880
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.
