A 4-layer PCB with a solid ground plane and a separate power plane is recommended. Keep the analog and digital traces separate and avoid crossing them. Use a common-mode choke or ferrite bead to filter the power supply lines.
Use a 50Ω termination resistor in series with the signal line, and a 50Ω termination resistor to ground in parallel with the signal line. This ensures impedance matching and minimizes signal reflections.
Power up the device in the following sequence: VCC, then VEE, then the digital supply (VDD). This ensures that the internal voltage regulators are properly initialized.
The thermal shutdown feature is enabled by default. If the device temperature exceeds 150°C, it will shut down. To handle this, implement a thermal monitoring system to detect overheating and take corrective action, such as reducing the device's power consumption or shutting it down temporarily.
Use a low-pass filter with a cutoff frequency of 100 kHz to 1 MHz to filter the output. A simple RC filter or a more complex active filter can be used, depending on the specific application requirements.
