KarenNEthank you for your respnose! But there some difference in timing diagrams between AD7949 and AD7682.
Here timing for AD7682:
Here timing for AD7949:
I don't understand: Can I write to AD7949 the same way as in AD7682?
Background/Use case:
4 analog sensors

Hi, Wayne.
I'm using Eval uMUX CED Rev 1.0. You can download it from Analog Devices AD7682 product page here: http://www.analog.com/en/analog-to-digital-converters/ad-converters/ad7682/products/EVAL-AD7682/eb.html
Let me know if this helps.

Hi everyone
I am using AD7682. The output of AD7682(SDO) is quite strange, which is shown in the diagram.
System description:
AD7682 is controlled by a microcontroller. The AD7682 CFG is configured as 0b11110010110001. Read After Conversion mode is…
对不起，我把ADC名字打错了，我们使用得是AD7682芯片，
Hi Richie,
The AD7682 can only be operated in either in a Unipolar or Pseudo-Differential mode, which means that the AD7682’s positive input swings between 0V and Vref and its negative input is always connected to either a ground OR a fixed DC value…
Erp- make that AD7682.

Hi,
ADC AD7682 have digital SPI connection but no digital grounding specified in the package.
As per datasheet " At least one ground plane should be used. It can be common or split between the digital and analog sections. In the latter case, the planes…
