Design Notes

The AD4083BCPZ operates from a 1.8 V analog supply and a 1.8 V digital supply. It is recommended to use separate low-noise LDOs for AVDD and DVDD to minimize digital noise coupling. Place 0.1 uF and 10 uF decoupling capacitors close to each supply pin. The integrated LDO regulators help, but external decoupling is still essential for optimal performance.

For the CSPBGA package, ensure proper PCB layout with a solid ground plane. Route the analog input and reference traces away from digital signals. Use a ground plane under the ADC to minimize noise. The integrated decoupling capacitors reduce external component count, but additional external capacitors may be needed for the reference and supply pins. Follow the layout guidelines in the datasheet.

Avoid driving the analog input beyond the supply rails. Use a suitable driver amplifier with low output impedance. Ensure the reference voltage is stable and well-decoupled. The Easy Drive architecture reduces input drive requirements, but a buffer may still be needed for high-impedance sources. Also, ensure the digital interface timing meets the specifications to avoid data corruption.
