DAC8811 www.ti.com SLAS411B – NOVEMBER 2004 – REVISED FEBRUARY 2007 THEORY OF OPERATION The DAC8811 is a single channel current output, 16-bit digital-to-analog converter (DAC). The architecture, illustrated in Figure 17, is an R-2R ladder configuration with the three MSBs segmented. Each 2R leg of the ladder is either switched to GND or the IOUT terminal. The IOUT terminal of the DAC is held at a virtual GND potential by the use of an external I/V converter op amp.
