The accuracy of the reference against which the voltage is measured - using any of the above references - is at best only 5. To capture the sound applied. 25V V IN+ V IN V REF EXTERNAL 2. 3v to 5v I needed to make some minor changes to EmonLib to get it to run the ADC at 12bits rather than 10bits. shows an analog signal applied to the input of the ADC, which then is converted to digital words at the sampling frequency (Fs) applied to the ADC clock. I think the best place to start is the input and output system (I/O). When designing an ADC. This is very useful when we want to do some processing on physical quantities, which are normally analog in nature. ADAC click is an 8-channel 12-bit ADC, DAC and GPIO.
