Hello,
is it possible to replace the AD7949 bye the AD7689 without changing the software? How does the SPI output looks like?
I hope you can share more infomation or links.

Hello, everyone. I am trying to measure thermistor voltage to check the temperature.
In this case, I have designed a circuit like the above one, and I connected 2 wires to AD7689's IN0 and IN1.
The VTH(+) is connected with IN0 and VTH(-) is connected…
我在使用ad7689时发现ad7689包输入电压抬高了1.5v,本来dcdc输出为5.1v装上ad7689就变为6.5v,还有我使用内部参考源4.096v,发现基准源不对,一直在跳变下面是我的原理图,
Hi all,
I am using AD7689 in my design.
Please let me know if you have any information on the min and max values regarding the temperature drift of the internal reference.
BestRegards,
Takahiro
