Design Notes
The AD4854BCPZ requires a clean 5V analog supply. Use a low-noise LDO regulator, such as the ADP151, to power AVDD. Decouple each supply pin with a 10uF ceramic capacitor and a 0.1uF capacitor placed close to the pin. The integrated supply decoupling capacitors reduce external requirements, but additional decoupling is recommended for optimal performance.
For best performance, use a solid ground plane and separate analog and digital ground planes if possible. Place the AD4854BCPZ away from high-speed digital circuits to minimize noise coupling. Route differential input traces as matched pairs and keep them short. Use a 4-layer PCB with dedicated power and ground planes for optimal signal integrity.
Ensure the input common-mode voltage is within the specified range to avoid clipping. The wide common-mode range allows flexibility, but verify the absolute maximum ratings. Do not exceed the supply voltage on any pin. Also, ensure the reference voltage is stable; use a low-noise reference if external reference is used. Follow the layout guidelines in the datasheet to achieve full 20-bit performance.
