The resolution of an 8 bit DAC will be:

Question

Answer 1

Resolution: 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 \( = \frac{{1}}{{{2^8} - 1}} = \frac{{1}}{{255}}\)
