The resolution of a 12-bit A/D converter having a full-scale analog input voltage of 5 V is

The resolution of an Analog to Digital (A/D) converter can be calculated using the formula:

Resolution = Full Scale Voltage / (2^n - 1)

where n is the number of bits.

In this case, the full scale voltage is 5V and the number of bits is 12.

So, the resolution would be:

Resolution = 5V / (2^12 - 1) = 5V / 4095 = 0.00122 V or 1.22 mV

So, the resolution of a 12-bit A/D converter having a full-scale analog input voltage of 5 V is 1.22 mV.
