System Architecture

The HAL 82x

sensors are produced in a

proven automotive submicron CMOS tech-

nology.

The HAL 82x features a temperature-com-

pensated Hall plate with choppered offset

compensation, an A/D converter, digital sig-

nal processing, a push-pull output, an

EEPROM memory with redundancy and

lock function for the calibration data and the

data register information, a serial interface

for programming the EEPROM, and protec-

tion devices on all pins.

The HAL 82x is programmable by modulat-

ing the supply voltage. No additional pro-

gramming pin is needed.

The internal digital signal processing is a

great benefit because analog offsets, tem-

perature shifts, and mechanical stress do

not degrade the sensor accuracy.
