A. Using R-2R ladder type DAC B. Multiplying DACs C. Using monolithic DAC D. Using hybrid DAC
Explanation: Usage wide range of resistors is the limitation of binary weighted resistor type DAC, this can be avoided by using R-2R ladder type DAC Where only two value of resistor are required. 11. Find output voltage equation for 3 bit DAC converter with R and 2R resistor?
