Interfacing to the Analog World - Technical MCQs

Q1:

If the range of output voltage of a 6-bit DAC is 0 to 15 volts, what is the step voltage of the output?

A 0.117 volt/step

B 0.234 volt/step

C 2.13 volts/step

D 4.26 volts/step

ANS:B - 0.234 volt/step

Here,

The Step size= V(r)/2^n.
Full scale voltage=Vr=15,
2^6=64,
Step size=15/64 = .234.
