In the NuMicroTM family, the power distribution is divided into three segments:
1. Analog power from AVDD and AVSS provides the power for analog components operation;
2. Digital power from VDD and VSS supplies the power to the internal regulator with a fixed 1.8 V power for digital operation and I/O pins.
(Except NUC100/120 AN, NUC100/120 BN and NUC130/140 CN and M051 AN Series will be 2.5V.)
3. USB transceiver power from VBUS offers the power for operating the USB transceiver (for NuMicro® USB Series only).
The operating voltage for ADC converter is 0 ~ VREF. Analog power (AVDD) should be the same voltage level of the digital power (VDD), otherwise the leakage occurs.
Below figure is an example for the power architecture of NUC122 Series.
What is the operating voltage for ADC converter?
