Bro which type of op amplifier is used in both dac and inverted dac converter. Is it related to current to voltage converter op amp? Please mention it bro. Adhi cheppaledu.
In R-2R ladder ADC, the analysis is carried out using NODE VOLTAGES. It's said to be operated in voltage mode. If you watch carefully, in INVERTED R-2R LADDER ADC, branch currents are used in the analysis. So it is said to be operated in current mode. We don't speak about voltage to current conversion or vice versa. Op-amp is same in both the cases. My experience says, in the exam poin of view, the question is straight forward ask 1 Draw and explain R-2R ladder ADC 2. Draw and explain inverted R-2R ladder ADC. If you find a messy and confusing question regarding this send me the question in picture @9441727101. Let us solve it together.
