We want to use the ADC of the AM3354 with internal voltage reference. So how must we connect the VREFP and VREFN pins ?
Datasheet SPRS171G describes:
"VREFP and VREFN must be tied to ground if the internal voltage reference is used."
Errata SPRZ360F describes: (TSC_ADC VREFP terminal not connected to VDDA_ADC and VREFN terminal not connected to VSSA_ADC)
"Insert a series resistor on each VREFP and VREFN terminal with a 0.1uF decoupling capacitor connected directly to each VREFP and VREFN terminal."
So do I need to connect the VREFP and VREFN with a series resistor and a 0.1uF to ground ? How should be the value of the resistor ?
Thanks and with best regards
