Unique Features
CMOS Hall IC Technology
The chopper stabilized amplifier uses switched
capacitor techniques to eliminate the amplifier off-
set voltage, which, in bipolar devices, is a major
source of temperature sensitive drift. CMOS
makes this advanced 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
contributes to lower physical stress and less
power consumption.
Installation Comments
Consider temperature coefficients of Hall IC and
magnetics, as well as air gap life time variations.
Observe temperature limits during wave solder-
ing.
Applications
If reverse supply protection is desired, use a re-
sistor in series with the V
DD
pin. The resistor will
limit the supply current (Fault), I
DD
, to 50 mA. For
severe EMC conditions, use the application circuit
on this page.
