### What is the resolution of a digital-to-analog converter (DAC)?

Options

A : It is the comparison between the actual output of the converter and its expected output.

B : It is the deviation between the ideal straight-line output and the actual output of the converter.

C : It is the smallest analog output change that can occur as a result of an increment in the digital input.

D : It is its ability to resolve between forward and reverse steps when sequenced over its entire range.

### The practical use of binary-weighted digital-to-analog converters is limited to:

Options

A : R/2R ladder D/A converters

B : 4-bit D/A converters

C : 8-bit D/A converters

D : op-amp comparators

Options

D : monotonicity

### The primary disadvantage of the flash analog-to digital converter (ADC) is that:

Options

A : it requires the input voltage to be applied to the inputs simultaneously

B : a long conversion time is required

C : a large number of output lines is required to simultaneously decode the input voltage

D : a large number of comparators is required to represent a reasonable sized binary number

### What is the major advantage of the R/2R ladder digital-to-analog (DAC), as compared to a binary-weighted digital-to-analog DAC converter?

Options

A : It only uses two different resistor values.

B : It has fewer parts for the same number of inputs.

C : Its operation is much easier to analyze.
