A 4-layer PCB with a solid ground plane and a separate power plane is recommended. Keep the analog and digital grounds separate and connect them at a single point. Use a 10nF capacitor between the VCC and GND pins to filter out noise.
Ensure good airflow around the device, and avoid blocking the airflow with components or obstacles. Use a heat sink if the device is expected to operate in high-temperature environments. Monitor the device temperature using the thermal monitoring pin (TMP) and take corrective action if it exceeds the specified range.
The recommended input voltage range is 4.5V to 5.5V. Operating the device outside this range may affect its performance and reliability.
Power up the device in the following sequence: VCC, AVCC, and then DVCC. Power down the device in the reverse sequence. Ensure that the power supplies are stable and within the specified range before enabling the device.
The MAX20404AFOB/VY+ has built-in ESD protection, but it's still recommended to follow proper ESD handling procedures during assembly and testing. Use an ESD wrist strap or mat, and ensure that the device is stored in an ESD-safe environment.
