ADC Connections ADC Connections if the ADC is Not Used It is recommended 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: • VDDA – Connect to VDDIO • VSSA – Connect to VSS • VREFLO – Connect to VSS • ADCINAn, ADCINBn, VREFHI – Connect to VSSA When the ADC module is used in an application, unused ADC input pins should be connected to analog ground (VSSA). NOTE: Unused ADCIN pins that are multiplexed with AIO function should not be directly connected to analog ground. They should be grounded through a 1-k Ω resistor. This is to prevent an errant code from configuring these pins as AIO outputs and driving grounded pins to a logic-high state. When the ADC is not used, be sure that the clock to the ADC module is not turned on to realize power savings. |
