Hey folks,
I am currently working on a small project that involves using the AD7329 ADC. For development purposes, I have been provided with an evaluation board, but I have encountered some challenges that I hope you can assist me with. The evaluation board is connected to a Raspberry Pi Pico (RP2040) via SPI. I am able to receive data, but the values obtained are not quite plausible. I have used the AD7329's internal reference voltage, but I haven't been able to verify if the evaluation board has a 680nF capacitor connected to the REFin/REFout pin. Additionally, the evaluation board's guide mentions an onboard AD780, but it does not provide any further explanation on how to utilize it. Could you please assist me by answering my questions regarding the presence of a 680nF capacitor on the board and providing guidance on using the onboard AD780?
