Design Notes
Provide clean, low-noise power supplies for VDD_5V and VDD_1.8V. Use low-dropout regulators (LDOs) with low output noise and adequate decoupling capacitors (e.g., 10uF and 0.1uF) close to the ADC pins. The integrated bypass capacitors in the package help, but external decoupling is still recommended for optimal performance.
Use a solid ground plane and minimize trace lengths for analog inputs and reference. Keep digital signals away from analog inputs to reduce noise coupling. Follow the layout guidelines in the datasheet, including proper placement of decoupling capacitors and avoiding ground loops.
Ensure the reference voltage is stable and low-noise. Use a precision reference like the ADR4550. Also, verify that the input signal is within the common-mode range and does not exceed the supply rails. The Easy Drive architecture reduces input current, but proper drive amplifier selection is still important for settling time.
