The resolution of an 8 bit A/D converter is

The resolution of an 8-bit A/D (Analog to Digital) converter is calculated using the formula:

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

Where:

• Full Scale Range is the maximum analog input value that the A/D converter can handle.
• n is the number of bits, in this case, 8.

Assuming a Full Scale Range of 5V (a common value), the resolution would be:

Resolution = 5V / (2^8 - 1) = 5V / 255 ≈ 0.0196V or 19.6mV

So, the resolution of an 8-bit A/D converter with a Full Scale Range of 5V is approximately 0.0196V or 19.6mV. This means that the smallest change the A/D converter can detect is around 19.6mV.
