Lower supply voltage than AD7980BRMZ (vs AD7980BRMZ)

Design Notes

Provide a clean 1.8V analog supply (VDD) and a separate digital interface supply (VIO) to minimize noise coupling. Use low-dropout regulators with low output noise, and place 100nF and 10uF decoupling capacitors close to the VDD and VIO pins. The AD4000BRUZ consumes low power, but proper decoupling is critical for achieving the specified 94 dB SNR.

For optimal performance, keep the analog input traces short and shielded from digital signals. Use a solid ground plane and avoid routing digital lines under the ADC. Place the reference decoupling capacitor (10uF) close to the REF pin. Follow the layout guidelines in the AD4000 datasheet (Rev. F) to minimize parasitic capacitance and maintain linearity.

Ensure the input signal is within the specified common-mode range and does not exceed the supply rails. Use a low-noise driver amplifier, such as the ADA4077-1, to buffer the input and provide sufficient settling time. Avoid driving the input with high-impedance sources, as this can degrade SNR. Also, verify the SPI timing requirements to prevent data corruption.
