WebIn the popular ‘binary weighted’ resistor network shown in outline in Figure 10.4, the resistors have values of R, 2R, 4R, 8R, and so on, in multiples of powers of 2, and each resistor is switched into circuit as its own associated bit is set equal to 1. When the input bit associated with any resistor is equal to 0, that resistor is not ... Webthat is, the resistors are binary weighted. Single-pole, double-throw switches are used, and each resistor that is not supplying current from the reference voltage Vr is connected to ground. The switches of this …

Max Circuit: Digital To Analog Converter Circuit Diagram

WebA 10% tolerance means the actual value of the 78.125 ohm resistor may fluctuate within +/- 10%. You can do better with a 1% tolerance resistor but how do you get out to 3 significant figures of resolution? This weighted binary/scaled approach fails us when we need more than just a few bits of resolution. What are we to do? WebAn alternative to the binary weighted input DAC is the R-2R Ladder, which uses fewer unique resistor values thus does not require precision resistors. A disadvantage of the former DAC design was its small belt size in cm
