#28142 Voltmeter for measuring millivolts

Posted by MDS on 26 April 2012 - 01:33 PM

The chip has a 12bit ADC on it @12 bit it reads in a resolution of .000805V thats 3.3V / 4096. So just take the number from the analog channel and multiply it by .000805 for the voltage. 150mV would be 186 form the analog channel.
