The HAL® 85x complement the existing Hall- effect sensor family HAL 8xx. 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 with 32 setpoints with a resolution of 9 bit 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 TO-92UT.
