Design Notes
Provide a clean analog supply (AVDD) using a low-noise LDO. The ADS1262 requires 4.75V to 5.25V on AVDD and 2.7V to 5.25V on DVDD. Place 0.1Β΅F and 10Β΅F decoupling capacitors close to the AVDD and DVDD pins. A separate analog ground plane is recommended to minimize noise coupling.
For optimal performance, use a 4-layer PCB with dedicated analog and digital ground planes. Route analog inputs away from digital traces to avoid crosstalk. Place the reference bypass capacitor (10Β΅F) close to the REFIN+ and REFIN- pins. Use a star-ground topology to connect analog and digital grounds at a single point.
Avoid exceeding the absolute maximum ratings on any pin. Ensure the reference voltage is stable and within the specified range. Do not leave unused analog inputs floating; connect them to AVSS or a defined voltage. The SPI interface should be operated at the correct logic levels (DVDD) to prevent communication errors.
