Programmable Hall Sensors with arbitrary output HAL85x

The HAL 85x complements the existing Hall sensor family
HAL 8xy. Both universal magnetic field sensors provide an arbitrary
output signal. The sensors are produced in submicron
CMOS technology.
in combination with a rotating or moving magnet, the sensors
can be employed for angle, distance, and level measurements.
The sensors provide either a pulse-width-modulated (PWM)
output signal or a serial Biphase-M output.
Major characteristics like magnetic field range, output characteristic,
output format sensitivity, shift (duty cycle of the PWM output
signal or the serial output word), PWM period, low and high
current and the temperature coefficients can easily be adjusted
to the magnetic circuit (linear and quadratic) by programming
the non-volatile memory. The output characteristic can be set
via 32 setpoints.
The sensors were designed to translate a linear magnetic field
into an arbitrary output signal or a non-linear magnetic field into
a linear output signal.
The sensors are available in the very small leaded package
TO92UT.
