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 magnetic, 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
ESD Precautions
Electronic semiconductor products are sensitive to Electro Static Discharge (ESD). Always observe Electro
Static Discharge control procedures whenever handling semiconductor products.
