The pin configuration of the DACx1416 has been designed in such a way that the analog, digital, and power pins are spatially separated from each other, which makes the PCB layout simple. An example layout is shown in Figure 11-1. As evident, every power supply pin has a 0.1-µF capacitor close to the pin. Make sure to lay out the analog and digital signals away from each other, or on different PCB layers. Make sure to provide an unbroken reference plane (either ground or VIO) for the digital signals. The higher frequency signals, such as SCLK and SDI, must have appropriate impedance termination in order to address signal integrity.
