Posted on May 17, 2011 at 13:48Thank you very much for your inputs. I used a potential divider with 5K and 1K and have the taken the output to feed the ADC. Here the current did not exceed 3.3mA which is the high current to ADC. I am planning to use...
Posted on May 17, 2011 at 13:48I meant the input current for the ADC channel only. In the data sheet, I could see the external impedance as 50KOhms. If the input voltage range to the ADC is 0 to 3.3V, then is the max input current = 3.3/50K = 0.066m...
Posted on May 17, 2011 at 13:46I think I failed to explain my doubt.Yes, I have seen the responses at Keil. From the schematics, I could understand that the pin PC4 in Extension connector is connected to the on-board pot RV1. I I was confused where...
