System Architecture
The HAL 1820 sensor is produced in a
proven submicron CMOS technology.
The HAL 1820 features a temperature-com-
pensated Hall plate with choppered offset
compensation, an A/D converter, digital sig-
nal processing, an analog 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 1820 is programmable by modu-
lating 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.
