Steve is right! If you reference analog input signal to a ground contaminated with digital ground return currents, voltage spikes of several 100mV can be superimposed. If your input voltage range is 0V to 5V, then even a 6bit ADC makes no sense!
Whether you can benefit from a ADC providing a higher resolution mainly depends on YOUR design (PCB routing, etc.)! It's wise to follow recommendations given in datasheet... Kai |
