Mexico, (+ United Kingdom, (+ Power dissipation of Binary weighted Resistors Circuit is very high. 92) Current steering DAC has advantage of constant output impedance and high . New Zealand, (+ Cambodia, (+ A.Require wide range of resistors. Oman, (+ 7. Increasing the resolution decreases the step size between the output levels that lead to smooth and precise analog output. Disadvantages of Digital to Analog Converter (DAC) The disadvantages of DAC are: Voltage levels must be exactly the same for all inputs in Weighted Resistors DAC. That means zero volts is applied at the non-inverting input terminal of op-amp.According to the virtual short concept, the voltage at the inverting input terminal of op-amp is same as that of the voltage present at its non-inverting input terminal. Counter type ADC: The D to A converter can be easily turned around to provide the inverse function A to D conversion. Russia, (+ For example, we may have a 4-bit digital logic circuit that ranges from 0000 to 11112, (0 to F16) which a DAC converts to a voltage output ranging from 0 to 10V. 2) Number of bits can be expanded by adding more sections of same R/2R values. As the number of bit increases, the range of resistance value increases. For example, an 8-bit DAC with TTL +5 inputs would produce a resolution of 0.039 (1/128*V) volts, while a 12-bit DAC would be 0.00244 (1/2048*V) volts per step (1 LSB) change of the input binary (or non-binary) code. A disadvantage of the former DAC design was its requirement of several different precise input resistor values: one unique value per binary input bit. d) Vo =K(d12-1+d22-2+.dn2-n) Maldives, (+ The proposed design ensures high conversion . 1,724. In the voltage domain, that is if the input signals are voltages, the addition of the binary bits can be achieved using the inverting summing amplifier shown in the above figure. eg.
