An ideal 6-bit DAC with zero offset gives output voltage of 0.1 V for an input ‘000010’. What is the output for input ‘001010'

An ideal 6-bit DAC with zero offset gives output voltage of 0.1 V for an input ‘000010’. What is the output for input ‘001010' Correct Answer 0.5 V

The output of a DAC (va) 

va= R × D

where R→ resolution of DAC, D → decimal equivalent of digital input

Given digital input 000010, va= 0.1 

The decimal equivalent of  000010 is 2 

va= R × D

0.1 = R × 2

R = 0.05

Now for input 010100

The decimal equivalent of 001010 is 10

va= 0.05 × 10

va = 0.5 V
