Apologies that the ADC you are using is not in the tool. The AD7667 datasheet gives a recommendation for the RC filter and a suitable driver. See Figure 26 and pages 18-19.

AD7667,.
AD7641 for next upgrade.
请问可以把锯齿波信号源的波形和AD7667采样到的码值的波形截图上来看一下吗？
可以接其它的DC源，比如低噪声LDO, 或参考电压，测一下AD7667链路的噪声水平吗？
您好。AD7667在INL，DNL，SNR，ENOB等性能上较AD7653均有提升。
Hi,
The AD7767 has a feature to make the part as the master where it can provide serial data clock and SYNC signal. The AD7667/AD7671 family has this feature you may check on these parts on the ADI site (http://www.analog.com/media/en/technical-documentation…
Hello!
I am now using an AD7667 conversion chip, and I use the internal reference voltage, the parallel model, but my output has been FF7F, through inspection , I found that the internal reference voltage on the pin of REF is about 0.3V, this means…
您们好，我现在在用一款AD7667的模数转换芯片，采用的是内部参考电压，并行模式，但我的输出一直都是FF7F，经检查发现内部参考电压引脚上的电压我0.5V左右，也就是说内部参考电压出问题了。可是我的PD,PDREF,PDBUF都为低，SER/PAR设置为高（即并行），采用的是IMPULSE模式。出现这个问题是什么原因呢？谢谢前辈们@的帮忙！
Hi Postino,
Here are some list of ADC that could be suitable for your application. You may also wanted to check the ADI website and do a parametric search and put in parameters on the ADC that you wanted to search. Please refer to the link below.
Hi vlad8016,
What Klaus mentioned are right. There are three most common types of ADC input structure a.) Single- Ended b.) Pseudo Differential c.) True Differential. From your description above I can see that you are looking for ADC that has a pseudo…
