11.1 Layout Guidelines
Analog inputs will provide best accuracy when referred to the GND pin or a supply with low noise. A separate, low-impedance ground plane for analog ground, which provides a ground point for the voltage dividers and analog components, will provide best performance but is not mandatory. Analog components such as voltage dividers must be located physically as close as possible to the ADC128D818.
