ATmega328P – measuring its own supply voltage III

Timing of the internal analog-to-digital converter of an ATmega328P with a 5 V supply voltage.

After the first two parts of this series ATmega328P – measuring its own supply voltage ATmega328P – measuring its own supply voltage II where I investigated the possibility of the Atmel ATmega series microcontrollers to select the internal bandgap voltage VBG as input for the analog-to-digital converter. Using the analog supply voltage AVcc as reference… Continue reading ATmega328P – measuring its own supply voltage III
