System Architecture
The HAL 3625 sensor is produced in a
proven submicron CMOS technology.
The HAL 3625 features temperature-com-
pensated Hall plates with choppered offset
compensation, two A/D converters for the
magnetic field information, a temperature
sensor with A/D converter, digital signal pro-
cessing, 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 program-
ming the EEPROM, and protection devices
on all pins.
The HAL 3625 is programmable by modu-
lating the output voltage. No additional pro-
gramming pin is needed.
The internal digital signal processing is of
great benefit because analog offsets, tem-
perature shifts, and mechanical stress do
not degrade the sensor accuracy.
