C8051F85x/86x internal ADC voltage reference?. on
I'm wondering, if I power the MCU with +3.0V, and using the internal voltage reference of 2.4V, am I still able to sample signals from 2.4-3.0V? The datasheet says that using a (stable) power supply as external voltage reference "can provide the ADC with added dynamic range". By how much? I'll only be sampling at an 8 bit resolution.
