DAC Coding Schemes

As digital signal processors (DSPs) have become more sophisticated and faster, the need for MDACs has declined. Data is digitized, the DSP scales the digital representation into the desired range, and then uses an ordinary DAC to generate a fresh analog signal. Nevertheless, if one needs a very high speed analog multiplier, there are times that an MDAC is the cheapest, easiest way to do it.
