설계 노트
Ensure clean power supply for the AD4080BCPZ-RL7. Use low-noise LDO regulators and place decoupling capacitors (0.1uF and 10uF) close to the VDD and VIO pins. A dedicated analog supply is recommended to minimize digital noise coupling.
For optimal performance, use a solid ground plane and separate analog and digital ground areas. Route the differential input traces with controlled impedance and keep them short. Place the reference decoupling capacitor close to the VREF pin to ensure stable reference voltage.
Avoid driving the analog input beyond the specified common-mode range. Use a proper input driver amplifier with sufficient bandwidth and low noise. Ensure the serial interface timing meets the datasheet specifications to avoid data corruption.
