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 star topology for the power supply and keep the high-current paths short and wide.
Use a heat sink with a thermal resistance of 10°C/W or lower. Ensure good airflow around the device. Use thermal interface material (TIM) to fill the gap between the device and the heat sink. Avoid blocking the airflow around the device.
Power up the device in the following sequence: 1) Power up the analog supply (AVDD), 2) Power up the digital supply (DVDD), 3) Apply the clock signal, and 4) Apply the input signal. This sequence helps prevent latch-up and ensures proper device operation.
Use a shielded enclosure, keep the analog and digital circuits separate, and use a common-mode choke to filter the power supply. Use a low-pass filter on the output stage to reduce high-frequency noise. Ensure good grounding and use a Faraday cage or a shielded cable for the output stage.
The recommended clock frequency is between 256 kHz and 512 kHz. A higher clock frequency can improve the signal-to-noise ratio (SNR) but may increase power consumption. A lower clock frequency can reduce power consumption but may degrade the SNR.
