Measuring the ADuCM320 temperature with the on on-chip temperature sensor shows large variations.
From the user guide, we get the formula as below,
T = ((VADC-1290)/4.394)+25;
May I know the conditions for the values of the constants used? (K (4.394 mV/°C) and 1290mV@25degC) ?
Are they from an ADC measurement at 80KSPS as the description in user guide?
How about ADC input buffer enabled or bypass?
