Translation:
I am using AD7768-4FMCZ evaluation board, and configure communication through SPI of MCU, MCU_GPIO reads DOUT0 data,
Based on this board, I have a question. AINx+/- of AD7768-4 supports differential signal or pseudo-differential signal input.
The pre-stage circuit of AINx+/- on the evaluation board is a buffer circuit composed of ADA4896-2.
If I want to test the input of the evaluation board through a single-ended signal, for example, the signal source IN is 0~1VDC, A0+_AMP
is connected to IN, and A0-_AMP is connected to 0V. Of course, the signal source GND will share the ground with the evaluation board.
Can it be applied like this?
Thank you very much for your reply in your busy schedule
Thanks
我正是使用AD7768-4FMCZ评估板,并通过MCU的SPI进行配置通讯,MCU_GPIO 读取DOUT0数据,
基于此板,我有个疑问
AD7768-4的AINx+/-支持差分信号或者伪差分信号输入,评估板 上AINx+/-的前级电路是ADA4896-2组成的缓存器电路,
如果我想要通过单端信号测试评估版输入,比如 信号源IN 0~1VDC,A0+_AMP接IN,A0-_AMP接0V 当然 信号源GND会与评估版共地
是否可以这样应用?
非常感谢您百忙之中的回复
谢谢
