Hi All
I have been trying to configure and use the AD7172-4 for about a week now and am not having much luck.
My Setup
Hello everone.
I have connected the EVAL-AD7172-4SDZ board to the SPI interface on a STM32F405 board. Writing to registers in the ADC seems to work fine, e.g. I can start a conversion in single conversion mode, set the ADC into standby mode or turn on…
Hi Muthu,
what is your signal swing at the output and noise requirement?
look at devices such as AD7172-2 or AD7172-4 as examples - buffered input scenarios with mux available as a ballpark.

After finally getting the above device to behave sensibly, I have come across another issue. While it does not completely stop me using the chip, I would like to get to the bottom of the issue.
From what I am aware, this device allows any of…
Hi Winio,
The analog and digital supplies to the AD7172 are independent and connected to separate pins to minimize coupling between the analog and digital sections of the device. As indicated on the datasheet, the PCB designed must have analog and digital…
Hi Sharvy,
Please check on the AD7124-8 and AD7172-4. These are some of the latest in the Sigma-Delta ADC family and are multi channel at 24bit resolution. Below is the link of the datasheet. Let me know if there are other concerns.
