Design Notes
Ensure that the AVDD and DVDD pins are properly decoupled with 0.1 Β΅F and 10 Β΅F capacitors placed close to the pins. The reference pin (REF) should also be decoupled with a 10 Β΅F capacitor to ensure stable operation. Use a low-noise LDO for the analog supply to minimize noise coupling into the ADC.
For optimal performance, use a solid ground plane and separate analog and digital ground areas, connecting them at a single point. Keep analog input traces short and shielded to reduce noise pickup. The exposed pad (EP) should be soldered to the ground plane for thermal and electrical performance.
Avoid driving the analog inputs beyond the supply rails, as this can cause latch-up or damage. Ensure that the SPI interface timing meets the datasheet specifications, especially the setup and hold times. When using the internal reference, do not load it with excessive capacitance, as this can cause instability.
Compliance Information
