应用须知
- Design for a Wideband Differential Transimpedance DAC Output (Rev. A)PDF, 438 Kb, 修订版: A, 档案已发布: Oct 17, 2016
High-speed digital-to-analog converters commonly offer a complementary current output signal. Most output interface implementations use either a resistive load and/or a transformer to convert this current source signal to a voltage. Where a dc-coupled interface is required, a carefully designed differential transimpedance stage can offer an attractive alternative. Design considerations and options - Wideband Complementary Current Output DAC Single-Ended InterfacePDF, 597 Kb, 档案已发布: 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
