A 4-layer PCB with a solid ground plane and a separate power plane is recommended. Keep the sensitive analog circuitry away from the digital circuitry and ensure a low-impedance path for the power supply.
Use a shielded enclosure, keep the device away from high-frequency sources, and ensure proper grounding and decoupling. Follow the recommended PCB layout and use a common-mode choke or ferrite bead to filter the power supply.
The maximum allowed voltage on the output pins is VCC + 0.3V. Exceeding this voltage may damage the device.
Use a heat sink or a thermal pad to dissipate heat. Ensure good airflow around the device and avoid blocking the airflow. The maximum junction temperature is 150°C.
The recommended clock frequency is 16 MHz, but the device can operate up to 20 MHz. However, higher frequencies may require additional decoupling and filtering.
