2.1.6. ADC Voltage Reference
There is only one external VREF pin in each Intel® MAX® 10 device. Therefore, if you want to assign external voltage reference for both ADC blocks in dual ADC devices, share the same external voltage reference for both ADC blocks.
Intel recommends that you use a clean external voltage reference with a maximum resistance of 100 Ω for the ADC blocks. If the ADC block uses an internal voltage reference, the ADC block is tied to its analog voltage and the conversion result is ratiometric.
