请问一下AD7760的并行IO接口和控制IO接口能不能与MCU的IO直接连接呢？MCU的IO电平是3.3V。AD7760看了是差分信号输入，有没有大神做过单端输入呢？误差这方面怎样呢？能不能达到0.001%呢？
If this is the case you should use a pseudo differential ADC. It allows IN- to vary up to ~100mv or so from ground and the IN+ can go all the way to the ref value. There are pin compatible p-diff parts like the AD7660. However there are newer p-diff ADCs…
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…
Hi Henning,
We have some I2C ADC interface that may fit your application, you may check the AD799x. Just like to ask on when are going to use the trigger feature, is it when the pulse amplitude hit some kind of limit or outside the range? I am also…

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…
