A 4-layer PCB with a solid ground plane and a separate power plane is recommended. Keep the analog and digital grounds separate, and use a common ground point for the device. Ensure good decoupling and bypassing, and keep the layout as symmetrical as possible.
Use a high-quality, low-ESR capacitor (e.g., 10uF) for power supply decoupling, placed as close as possible to the device. Add additional decoupling capacitors (e.g., 100nF) for each power pin. Ensure the power supply is stable and within the recommended voltage range.
The recommended clock frequency is 25MHz, with a clock signal quality of <100ps jitter and a duty cycle of 40-60%. Ensure the clock signal is clean and free from noise and distortion.
Configure the device for the desired conversion rate and resolution. Ensure the analog input signal is within the recommended range (0-2.5V) and properly filtered. Use the internal reference voltage or an external reference voltage with a low noise and high stability.
Use a shielded enclosure, keep the device away from high-frequency sources, and use a common-mode choke or ferrite bead on the power supply lines. Ensure good PCB layout practices, such as separating analog and digital grounds, and using a solid ground plane.
