3. The 4.7 µF ceramic capacitor must be connected to one of the V_DD pin.
4. V_DDA and V_SSA must be connected to V_DD and V_SS, respectively.
Each power supply pair (V_DD/V_SS, V_DDA/V_SSA ...) must be decoupled with filtering ceramic
capacitors as shown above. These capacitors must be placed as close as possible to, or
below, the appropriate pins on the underside of the PCB to ensure good operation of the
device. It is not recommended to remove filtering capacitors to reduce PCB size or cost.
This might cause incorrect operation of the device.
