Figure 6: Definition of differential amplitude  
In the energy-saving mode the current consumption of  
the Hall sensors can be quartered. This also reduces  
the maximum rotating frequency by a factor of 4.  
After switch-on the amplification is increased until the  
setpoint amplitude is reached. The amplification is  
automatically corrected in case of a change in the  
input amplitude by increasing the distance between  
the magnet and the sensor, in case of a change in  
the supply voltage or a temperature change. The  
sine signals are therefore always converted into high-  
resolution quadrature signals at the optimum ampli-  
tude.

In the test mode (TEST = 0x43) the internal currents  
can be calibrated on Pin B. For this purpose, the cur-  
rent must be measured based on VNA and the CIBM  
register bits must be changed until the current is cal-  
ibrated to 200 µA. All internal currents are then cali-  
brated.
