PRODUCT INFORMATION
HAL 1821/1822/1823

System Architecture
The HAL 1821/1822/1823 sensors are pro-
duced in a proven submicron CMOS tech-
nology.
The HAL 1821/1822/1823 feature a temper-
V_DD
ature-compensated Hall plate with chop-
pered offset compensation, an A/D con-
verter, digital signal processing, an analog
output and protection devices on all pins.
The internal digital signal processing is a
great benefit because analog offsets, tem-
perature shifts, and mechanical stress do
not degrade the sensor accuracy.
