Design Notes
Provide a clean, low-noise 1.8V analog supply (VDD) and a separate digital supply (VIO) to avoid coupling digital noise into the analog circuitry. Use a low-dropout regulator (LDO) such as the ADP151 with a 10uF ceramic capacitor at the output. Decouple each supply pin with 0.1uF and 10uF capacitors placed close to the device.
For optimal performance, place the AD4000BRUZ close to the signal source and use short, direct traces for the analog inputs. Keep the reference input (REF) well-decoupled with a 10uF capacitor. Use a solid ground plane and avoid routing digital signals under the analog input traces. Follow the layout guidelines in the AD4000 datasheet for best results.
Ensure the input signal is within the specified common-mode range and does not exceed the supply rails. Use a low-noise amplifier to drive the ADC input, as the input capacitance can cause settling issues. Also, avoid floating the CNV pin; tie it to a logic high or low as needed. Refer to the datasheet for the recommended drive circuit.
