VREF O R 2R 4R 2(N-DR SN R 219 92 Rf= 2 = Figure 7: An N-bit D/A converter using a binary-weighted resistive ladder network. HI VO
[2 marks] Derive an expression for the output current i, from this circuit. [1 mark] Show that vo is only dependent on VREF and D by deriving its expression from the circuit. [2 marks] From this circuit, list two factors that directly affect the accuracy of the output voltage.
