設計說明
Provide a clean 5V analog supply and a separate digital supply (VIO) to minimize noise coupling. Use low-dropout regulators (LDOs) with low output noise, such as the ADP151, to power the ADC. Decouple each supply pin with a 10uF and 0.1uF capacitor placed close to the device.
Use a solid ground plane and separate analog and digital ground areas, connecting them at a single point. Place the ADC close to the signal source to minimize trace length. Route analog inputs away from digital traces to reduce crosstalk. Use a ground guard ring around the analog input pins.
Ensure the reference voltage is stable and low-noise. Use a precision reference such as the ADR4520. Avoid floating unused pins; connect them to ground or VDD as recommended in the datasheet. Do not exceed the absolute maximum ratings for input voltage and supply voltage.
