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