  1. AN-1150: Controlling the AD5111/AD5113/AD5115 Using a Traditional Dial Interface
    Application Note

    Miguel Usach Merino

    … pin is pulled low, the part reads the status of the U/D pin, incrementing or decrementing an internal counter at each CLK falling edge, as shown in Figure 2. Figure 2. Up/Down Interface Operation. The AD5111/AD5113/AD5115 digital potentiometers offer guaranteed low resistor tolerance errors of ±8% and up to ±6 mA current density, making them ideal choices for a mechanical potentiometer replacement. The low current consumption (750 nA typical) and 2 …
