I know that true differential SAR ADCs usually have narrow common mode input range around VREF. However, someADCs e. g. AD7641, AD7643, AD7644 do not specify the common mode range. Does this mean they don't have this limitation?
And in fact are there…
Hi Jebas,
PLease see attached list of the ADIs some of the latest differential ADCs with less tahn 2 LSB INL error. I have short listed this ADCs for DAQ systems application. I have included in the column on the file the throughput rate and full power…

Hi Karen,
Thank you for your advice.
I have donwloaded the evaluation software from AD7655 product page.
Downloaded technical note is attached. This document is preliminary technical note.
Is there any newest technical note ?
If you have it, please…
大家好!
最近看了《ADI模数转换器应用笔记,第一册》里面的AN-282:采样数据系统基本原理一节,里面讲了很多有关有效位数,噪声方面的内容,但我在实际的电路中发现,影响AD精度的原因主要是参考源和采样保持,如果选的参考源很好的话AD精度就会提高,外置的采样保持器往往比AD内部的采样保持器要好。
我的问题是:ADC的所有误差都有哪些?有没有这种讲所有误差并且有公式的资料没?我想计算下,再和实际的电路结果对比下,看看哪里可以改进。谢谢各位大牛!
