Design Notes

The AD7980ARMZ operates from a 2.5 V supply. Use a low-noise LDO to provide a clean supply voltage, and place a 0.1 µF and 10 µF decoupling capacitor close to the VDD pin. The reference voltage (REF) should be driven by a low-impedance source, such as a precision reference buffer, to maintain accuracy.

For optimal performance, keep the analog input traces short and shielded from digital signals. Use a solid ground plane and separate analog and digital ground areas, connecting them at a single point. Place the ADC close to the signal source to minimize noise pickup. Follow the layout guidelines in the datasheet (Rev. G) for best results.

Ensure the reference voltage is stable and within the specified range (2.4 V to 5.1 V). Avoid driving the analog inputs beyond the supply rails, as this can cause latch-up. The SPI interface should be operated within the specified timing; use short traces and proper termination to avoid signal integrity issues.
