hi every one
i am asking for your help brother in this qusyion
if the out put from a sensor is a voltage in the range 1-5v, what is the minimun number of A-D bits required to guarantee a resolution of 0.001v?
If the range is 1-5, it means you should measure 4V amplitude. So, 4V/0.001V=4000 steps or your ADC resolution should be at least 12 bits, because 2^12=4096.
