I have some questions about ADuM1402.
Our customer are using ADuM1402 at the automotive BMS application.
At mass production process they have to use Electromagnet.
They want to know the Magnetic force Influence to the device.
When powering only VDD1(2) a voltage appears on the un-powered VDD.
The leakage current is about 35uA.
The voltages on each of the ADUM1402 pins are as follows -
1, 7 - +5V1 supply
2, 8 - GND1
3 - 10k to GND1
4 - driven High by uC.
5 - uC…
Could anyone tell me an alternative for AD7685 and ADuM1402 in NI-Multisim13. Also not just in multisim please help me in finding an alternative for AD7685 and AduM1402.
Usually the chip get broken because of exceed the absolute maximum value specified in datasheet. Please check them in your circuit. At the same time, you can contact ADI sales for a failure analysis which could provide some clue for root cause…
ADum1400 ADum1401 ADum1402 ADum3400/01/02 ADum4400/01/02 都可以作为参考
Thanks for your advice, I am using one ADUM5402 & three ADuM1402 as per the recommendation. I am suing this isolation for RS422, so 10MBps data rate is sufficient I think.
