Does anyone know if AD7708 can interface with Arduino using the SPI interface? Looking through the datasheet, other microprocessors are mentioned but the not the Arduino. Thank you!
We do not have an available sample code for AD7708. Although, I have attached a sample code for AD7718 which is similar to AD7708. You may use this as a reference to start off with your code.
Thanks and Best Regards,

I connected the Vref1+ to 5V, Vref1- to 0V in my sch.I found that the AD data readed from the AD7708 can not reach to 65525 when the input valtage is 5.000V.
I have searched the furom and found the Reply " https://ez.analog.com/data_converters…
With the AD7708, we are experiencing a strange behavior with sudden changes of temperature.
If there is a rapid cooling of the device down to -40 Celsius, it happens that a reading is completely erroneous.
This behavior happened when…
在AD7718上，AINCOM可以缓冲或不缓冲，但引脚AIN1-AIN10始终是缓冲的。因此，AIN1-AIN10的绝对AIN电压限值为AGND + 100 mV至AVDD - 100mV。对于AINCOM，使能缓冲器时，限值为AGND + 100 mV至AVDD - 100 mV；禁用缓冲器时，限值为AGND - 30 mV至AVDD + 30 mV。
Thanks for your reply.
Unfortunately, I can't show you circuit diagrams as they will reveal sensitive company information, and I haven't got authority to do that. What I can tell you is, that through a header with SPI signals and…
I would like to use sigma-delta converters for a multi-channel (48) acquisition application. There is a stringent need for synchronicity between each converter in our application. I am interested in using AD7712 converters since it features…
