Part Number: CC2541
Hi
I use CC2541‘s ADC channel to measure the battery's voltage.
And VDD is supplied from battery directly. The reference votalge is external AVDD5.
As battery's voltage range is 3.2V-4.2V, i want to know whether these configuration can results in the accuracy of measurement to be poor.
and if the reference voltage is internal voltage which equals to 1.24V, the result whether will be better or not ?
