The recommended power-up sequence is to apply VDD first, followed by VDDA, and then the clock signal. This ensures proper device initialization and prevents potential latch-up conditions.
To minimize EMI and noise, it's recommended to keep the analog and digital grounds separate, use a solid ground plane, and place the device close to the analog signal sources. Additionally, use a common-mode filter or a ferrite bead to filter out high-frequency noise.
The maximum allowed capacitance for the analog input pins is 10nF. Exceeding this value may affect the device's performance and stability.
The device has a thermal pad on the bottom, which should be connected to a thermal plane or a heat sink to dissipate heat efficiently. Ensure good thermal conductivity between the device and the heat sink or thermal plane.
The recommended clock signal frequency range is 10MHz to 50MHz. Operating outside this range may affect the device's performance and stability.
