- Wider supply voltage range than MAX11166 (vs MAX11166)
Design Notes
The AD7980BRMZRL7 operates from a single 2.5V to 5.5V supply. Decouple the VDD pin with a 10uF ceramic capacitor and a 0.1uF capacitor placed as close to the pin as possible. The VIO pin should be connected to the digital interface supply (1.8V to 5V) and decoupled with a 0.1uF capacitor. Ensure the reference voltage (REF) is stable and low-noise; use a precision reference like the ADR4550 and decouple with a 10uF capacitor.
For optimal performance, use a solid ground plane and minimize trace lengths for analog input and reference signals. Keep the analog input traces away from digital traces to reduce coupling. Place the ADC close to the signal source to minimize noise pickup. Use separate analog and digital ground planes connected at a single point if possible. Follow the layout guidelines in the AD7980 datasheet for best results.
Ensure the analog input signal is within the specified input range (0V to REF) and is driven by a low-impedance source. The pseudo-differential input requires the IN- pin to be connected to a clean ground or a reference point. Avoid floating the SDI pin; tie it to GND or VIO if not used. Also, ensure the SPI timing meets the datasheet requirements to avoid data corruption.
