A 4-layer PCB with a solid ground plane and a separate power plane is recommended. Keep the analog and digital sections separate, and use a common ground point for the analog and digital grounds.
Use a high-impedance voltage source, and ensure the voltage sense lines are short and well-bypassed. Also, use a low-noise, low-impedance voltage reference, and consider using a voltage reference with a low temperature coefficient.
The maximum current that can be drawn from the VCC pin is 10mA. Exceeding this limit may cause the part to malfunction or reduce its lifespan.
The POR and BOR functions are enabled by default. To disable them, tie the POR/BOR pin to VCC. Ensure the power supply is stable and within the recommended operating range to prevent unwanted resets.
The recommended clock frequency for the ADC is between 1.5MHz and 2.5MHz. Operating outside this range may affect the ADC's accuracy and linearity.
