Notas de aplicación
- Wideband Complementary Current Output DAC Single-Ended InterfacePDF, 597 Kb, Archivo publicado: jun 21, 2005
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 - Superposition: The Hidden DAC Linearity ErrorPDF, 106 Kb, Archivo publicado: oct 2, 2000
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 output voltages or currents. When the contribution to the output voltage or current of each individual bit is independent of any other, it means that the device exhibits no superposition error or tha
