The customer performs the ADuM7441 chip isolation test, and some chips fail (3 out of 100). Under what conditions are these tests carried out at the ADI plant to isolate the ADuM7441? Can I get confirmation files?

I have a question about propagation delay of ADuM7441.

Where is the temperature at which the propagation delay is minimized?
Where is the temperature at which the propagation delay is the largest?
Or if there is a correlation between temperature and propagation…

I will not have the liberty to make distinct ground planes running down the midline of the ADuM7441. I am connecting my board that has an ADC to an DAQ card, using the ADuM7441 to separate my grounds. Given a 4-layer board with signal/ground/power/signal…

It is a question about ADuM7441.
Is there a graph of Propagation delay versus temperature, Propagation delay versus Supply voltage?
I would be pleased if you could show me.

Best regards

使用ADE7763采样交流220V的电能，采用非隔离电源（AC-DC）产生的5V电压，而MCU430的供电采用隔离电源（AC/DC），请问MCU访问ADE7763的SPI接口，该如何选择隔离器件？参考设计给出的HCPL2232价格太高了，ADUM7441是否可以？谢谢

Hi,

I was wondering if it was dangerous for the ADUM to unpower one side? All inputs on the unpowered side are connected by a pull down resistor and will not have any signal on it.

Thanks

Dave Lacerte
