Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFResolution: It is defined as the smallest change in the analog output voltage corresponding to a change of one bit in the digital input.
The percentage resolution (%R) of an n-bit DAC is:
\(\%R = \frac{1}{{{2^n} - 1}} \times 100\)
The resolution of an n-bit DAC with a range of output voltage from 0 to V is given by:
\(R = \frac{V}{{{2^n} - 1}}volts\)
Calculation:
Number of bits (n) = 8
Resolution \( = \frac{{1}}{{{2^8} - 1}} = \frac{{1}}{{255}}\)
