Figure 6-3. ADC Connections
ADC Connections if the ADC is Not Used
TI recommends that the connections for the analog power pins be kept, even if the ADC is not used.
Following is a summary of how the ADC pins should be connected, if the ADC is not used in an
application:
• V_DDA – Connect to V_DDIO
• V_SSA – Connect to V_SS
• V_REFLO – Connect to V_SS
• ADCINAn, ADCINBn, V_REFHI – Connect to V_SSA
When the ADC module is used in an application, unused ADC input pins should be connected to analog
ground (V_SSA).
When the ADC is not used, be sure that the clock to the ADC module is not turned on to realize power
savings.
