A digital-to analog converter (DAC) translates digital signals to analog signals. For example, a 12-bit DAC takes a 12-bit binary number, called an input code, and converts it into one of 4,096 analog - Interfacing op amps to high-speed DACs, Part 2: Current-sourcing DACsPDF, 617 Kb, Archivo publicado: oct 4, 2009

High-speed digital-to-analog converters (DACs) most often use a transformer-coupled output stage. In applications where this configuration is not practical, a single op ampdifferential to single-ended stage has often been used. This application note steps through the exact design equations required to achieve gain matching from each output as well as a matched input impedance to each of the DA
