Block Diagram
The IC consists of a chopped
hall-probe (mono-cell in the
centre of the chip) with a
chopped preamplifier. Next
there is a summing node for
threshold level adjustment.
The threshold switching is actu-
ally done in the main compara-
tor. A converter feeds a digital
calibration logic. This logic
monitors the digitalized signal
by looking for minimum and
maximum values and also cal-
culates correction values for
threshold adjustment. The
static switching level is simply
done by fetching a digital value
out of a PROM.
