웹Even using a divider is no good as the ADC is ratiometric - and gives the same value. There are two things you can do: 1. Use a voltage divider on the supply and feed in an accurate external voltage to Aref. 2. Use the internal bandgap 1V1 voltage reference. The internal bandgap is not without a problem - its initial accuracy is 10%! 웹A bandgap reference voltage is a voltage source that outputs a voltage proportional to the bandgap of a semiconductor. SI bandgap voltage (Silicon) references are most common, which output at ~1.2 V. GaAs can also be used to build a reference source with larger voltage output, thanks to its wider bandgap of 1.42 eV, as demonstrated in a recent ... 웹Gemeda MD, Han MS, Abebe AT, Kang CG.
