Suppose you set your DAC to $3\mathrm{.}0$V and turn it on$.$ Which statement is the most correct about the DAC's output voltage,Vdac $,$ in this situation?

will always be exactly equal to $3\mathrm{.}0$V

will always be slightly less than $3\mathrm{.}0$V

will always be much less than $3\mathrm{.}0$V

It is impossible to know without having information about the circuit
