The binary-weighted DAC is appropriate for DACs with low resolving power. This is because it requires a wide range of precise resistors to perform error-free operations for high-order DACs. It is impossible to maintain the accuracy of the weighted DACs and is expensive. This leads to the R-2R ladder technique, which implements only two resistors … Read more
In this tutorial, we will discuss the workings of a binary-weighted resistor DAC. It consists of an inverting amplifier op-amp and a string of weighted resistors to distinguish each bit starting from the LSB to the MSB position. Each resistor represents a digital bit to be converted into analog form. The maximum amount of information … Read more
