A. Weighted Resistor type DAC B. R-2R ladder type DAC C. Inverter R-2R ladder DAC D. All of the mentioned
Explanation: Current remain constant in each branch of ladder in inverted R-2R ladder DAC. So, the constant current implies constant voltage. The ladder mode voltage remain constant even when the input data changes. So, inverter R-2R ladder DAC is considered to be linear. 5. Multiplying DAC uses
