Q
The used ADC has tristate outputs. Is it neccessary to use pull up or downresistors at AduM1402 inputs ? And if not how is the behaivior of the AduM1402
output, if the ADC output is in high Z state ?
Hi,
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…
Hi,
We use two ADUM1402 to connect 74hc244 and then communicate separately with two groups of 74HC165D chips. The QH(PIN-9) of 74HC165D is connect directely to the AUDM pins. (Attach are the schematics for reference)
The question is that the ADUM140…
Hi !
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.

…Hi
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.
Thank You
ADum1400 ADum1401 ADum1402 ADum3400/01/02 ADum4400/01/02 都可以作为参考
Hi Brian,
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.
