Design Notes

Provide a clean, low-noise reference voltage to the REF pin. Use a precision reference such as the ADR4520 or ADR4550 for optimal performance. Bypass the REF pin with a 10uF ceramic capacitor to reduce noise and improve settling time.

Place decoupling capacitors (0.1uF and 10uF) close to the VDD and VIO pins. Use a solid ground plane and minimize trace lengths for the analog inputs. Keep digital signals away from analog input traces to reduce coupling.

Ensure the input signal is driven by a low-impedance source, such as an op-amp, to avoid sampling errors. Configure the SPI interface with correct clock polarity and phase (CPOL=0, CPHA=1) as per the datasheet. Do not exceed the absolute maximum ratings on any pin.
