How to determine the minimum voltage an ADC can measure.
What are the analysis we need to do for the same?
How to do the error budgeting of an ADC.
Minimum voltage will be determined by the ADC resolution. A 24-bit ADC can discern a much smaller voltage step than a 12-bit ADC. Perhaps a more useful approach would be to define the voltage you need to measure/resolve, the voltage range of the signal, then we can determine both the ADC architecture (SAR or DELSIG) and number of bits. This App Note should be very helpful in your determination: www.ti.com/lit/an/sloa249/sloa249.pdf .
This training presentation will also be helpful: TI Precision Labs - ADCs . And on this ADC Support Link: www.ti.com/product/ADS1281/support , scroll down to the "Introduction to "Designing with Delta-Sigma ADCs" Training Series and view this as well.
At your service,
