ref b) For the DAC circuit shown below, answer the following questions given that v = 15 volt. - Determine Iout and out if the following binary string are input at A to Ag: [0101 0111]. [3.5 Pts.] - How could the reference current I be reduced by half? In this case, what will be value of V at full scale (A, to A = HIGH)?
