Application Information
Note: The following information is given as a hint for the implementation of the device only and shall not be
regarded as a description or warranty of a certain functionality, condition or quality of the device.
Figure 14 shows a simplified application circuit. V_DDA and V_DD need to be reverse protected. Also the Resistors at
the digital pins are for reverse polarity protection.
