works. There is no limit to the resolution of the ADC data word. Once
you actually understand how the ADC works, you will see that. But as
long as you keep talking about the constituent parts, you will not see it.

you said, "Y is " how can I use the GA144's VCO to measure very small
analog changes on its input pin with very high resolution?" Answer - see
above." So what is an ANALOG that you are measuring changes in?
