Unique Features

CMOS Hall IC Technology

The chopper stabilized amplifier uses switched capacitor techniques to eliminate the amplifier offset 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 and life time variations. Observe temperature limits

during wave soldering. Typical IR solder-reflow profile:



No Rapid Heating and Cooling.



Recommended Preheating for max. 2minutes at 150

C



Recommended Reflowing for max. 5seconds at 240

C
