31 Buffered ADC reference voltage supply.
35 Unbuffered ADC reference voltage supply.
37 adi,internal-ref-microvolt:
39 Internal reference voltage selection in microvolts.
41 If no internal reference is specified, the channel will default to the
42 external reference defined by vrefin-supply (or vref-supply).
43 vrefin-supply will take precedence over vref-supply if both are defined.
45 If no supplies are defined, the reference selection will default to
46 4096mV internal reference.
