Hi everyone, I'm using a 4 bit ADC to convert a voltage that can potentially be between 0 and 3.3V. I end up with approx. 3.3/16 = 0.2V step size for each code which is not good enough. However I am only interested in the
0.6V to 1.4V range (0.4V swing centered around 1V). Is there a way to get the ADC converting only those values? Clipping is acceptable if the voltage is below 0.6 or above 1.4V.I could potentially get 0.8V/16 = 0.05V precision if the ADC was not wasting all those codes on don't care input values.
I guess this is a standard problem but I can't really find an easy solution.
Thanks,
David
