Question 331Electricity & Electronics - Assistant Engineer

The correct answer is A. An 8-bit digital to analog converter (DAC) has a resolution of 256 (2^8) possible output levels. With an analog output voltage range of 10 volts, the voltage step size or resolution of the DAC is 10 volts / 256 = 0.039 volts (or 39 millivolts). The other options are incorrect because they do not accurately reflect the voltage resolution of an 8-bit DAC with a 10 volt output range.
