Design Notes

The AD7980BRMZRL7 operates from a single 2.5 V to 5.5 V supply. Decouple the VDD pin with a 10 µF ceramic capacitor and a 0.1 µF capacitor placed close to the pin. The reference voltage (REF) should be decoupled with a 10 µF capacitor to ensure stability and low noise. Power consumption scales with throughput, so reducing the sampling rate can significantly lower power draw in battery-powered applications.

For optimal performance, use a solid ground plane and keep analog and digital grounds separate, connecting them at a single point. Place the ADC close to the signal source to minimize trace length and reduce noise pickup. Use short, wide traces for the analog input and reference pins. Avoid routing digital signals near the analog input to prevent crosstalk.

Ensure the analog input is driven by a low-impedance source to avoid sampling errors. The input capacitance of the ADC can cause settling issues if the source impedance is too high. Use an op-amp buffer if necessary. Also, the reference voltage must be stable and well-decoupled; any noise on REF directly affects conversion accuracy. Verify that the SPI timing meets the datasheet specifications to avoid communication errors.
