WebA model of the linear R-2R ladder digital-to-analog converter (DAC) is developed in terms of the ratios of the effective resistances at the nodes of the ladder. Web5 de jun. de 2016 · It's easy to set these two equations equal to each other and solve for R OUT: − V R E F R F R O U T = − R F ⋅ n 2 N ⋅ V R E F R. R O U T = R 2 N n. When the input code is all-zeros, none of the R-2R legs are connected to the output node, so R OUT is infinite. When the input code is all-ones, R OUT is nearly equal to R. WebOne of the most common DAC building-block structures is the R-2R resistor ladder network shown in Figure 4. It uses resistors of only two different values, and their ratio is 2:1. An N-bit DAC requires 2N resistors, and they are quite easily trimmed. There are also relatively few resistors to trim. 2R 2R 2R 2R 2R. RRR. Figure 4: 4-Bit R-2R ... darst funeral home humble texas
