SS248
CMOS Omnipolar High Sensitivity Micropower Hall Switch
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 150C
Recommended Reflowing for max. 5seconds at 240C
