Suppose that a 3- digit BCD digital- to- analog converter has a full- scale output of 49.95 ma. What is the resolution of the DAC?
A) 12 µA
B) 50 µA
C) 11 µA
D) 49 µA

The resolution of a DAC is calculated by dividing the full-scale output range by the number of discrete output levels. For a 3-digit BCD DAC, there are 10^3 = 1000 discrete levels (since each digit can represent values 0-9, and there are 3 digits). Therefore, the resolution is 49.95 mA / 1000 = 0.04995 mA, or 49.95 µA. Rounding to the nearest whole number gives 50 µA.
