PRODUCTION DATA.
The pin out of DACx1408 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 70. As evident, every power supply pin has a 0.1-µF capacitor close to it. The layout of the analog and digital signals should be laid out away from each other or on different PCB layers. It is recommended to provide an unbroken reference plane (either ground or VIO) for the digital signals. The higher frequency signals such as SCLK and SDI should have appropriate impedance termination in order to address signal integrity.
