Unique Features
CMOS Hall IC Technology
pacitor techniques to eliminate the amplifier offset
voltage, which, in bipolar devices, is a major source
of temperature sensitive drift. CMOS makes this ad-
vanced technique possible.
The CMOS chip is also much smaller than a bipolar
chip, allowing very sophisticated circuitry to be
placed in less space. The small chip size also contrib-
utes to lower physical stress and less power con-
sumption.
Installation
Consider temperature coefficients of Hall IC and
magnetics, as well as air gap life time variations. Ob-
serve temperature limits during wave soldering.
