The following circuit diagram shows the basic 2 bit R-2R ladder DAC circuit using op-amp, Here only two values of resistors are required i,e, R and 2R, The number of digits per binary word is assumed to be two i,e, n = 2, The switch positions decides the binary word i,e, B1 B0 The typical value of feedback resistor is Rf = 2R, The resistance R is normally selected any value between 2,5

DAC 8-Bit Using R-2R Ladder

The R-2R Ladder is one of the most popular DAC converters because of its simplicity, It utilizes only two values of resistors and it can be extended to any number of bits, Furthermore, its output impedance is always equal to R regardless of the number of …

R-2R Digital-to-Analogue Converter R-2R DAC

R-2R DAC Circuit with Four Zero LOW Inputs , The ouput voltage for an inverting operational amplifier is given as: R F /R IN*V IN, If we make R F equal to R, that is R F = R = 1, and as R is terminated to ground 0V, then there is no V IN voltage value, V IN = 0 so the output voltage would be: 1/1*0 = 0 volts, So for a 4-bit R-2R DAC with four grounded inputs LOW, the output voltage
