VDACOptional external reference voltage for on-chip DACs. There is a 100-pF capacitor to VSSA on this pin whether used for ADC input or DAC reference which cannot be disabled. If this pin is being used as a reference for the on-chip DACs, place at least a 1-µF capacitor on this pin.I8887
VREFHIAADC-A High Reference. In external reference mode, externally drive the high reference voltage onto this pin. In internal reference mode, a voltage is driven onto this pin by the device. In either mode, place at least a 2.2-µF capacitor on this pin. This capacitor should be placed as close to the device as possible between the VREFHIA and VREFLOA pins. Do not load this pin externally in either internal or external reference mode.I/O25161614
VREFHIBADC-B High Reference. In external reference mode, externally drive the high reference voltage onto this pin. In internal reference mode, a voltage is driven onto this pin by the device. In either mode, place at least a 2.2-µF capacitor on this pin. This capacitor should be placed as close to the device as possible between the VREFHIB and VREFLOB pins. Do not load this pin externally in either internal or external reference mode.I/O24161614
VREFHICADC-C High Reference. In external reference mode, externally drive the high reference voltage onto this pin. In internal reference mode, a voltage is driven onto this pin by the device. In either mode, place at least a 2.2-µF capacitor on this pin. This capacitor should be placed as close to the device as possible between the VREFHIC and VREFLOC pins.
