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 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.
