Design Notes
Ensure clean power supplies for the ADAQ7769-1BCPZ. Use low-noise LDO regulators and decouple each supply pin with 0.1uF and 10uF capacitors. The device's performance is highly dependent on supply noise, so proper filtering is critical for achieving the specified 24-bit resolution.
For optimal performance, place the reference decoupling capacitors close to the REFIN and REFOUT pins. Use a solid ground plane and avoid routing digital signals near the analog input pins. The datasheet recommends a 4-layer PCB with dedicated analog and digital ground planes to minimize noise coupling.
Do not exceed the absolute maximum ratings for supply voltage and input pins. Ensure the reference voltage is within the specified range (1V to VDD_ADC) to avoid incorrect conversions. Also, configure the device correctly via SPI or pin strapping to match your application's sample rate and gain settings.
