FAQ
你好,
我们在产品上验证ADuM6401时发现Viso管脚没有5V电压输出(Vsel与Viso连接);尝试采用直接用外部DC 5V电源供电(无限流),Viso仍然没有5V输出。请帮忙分析一下原因,谢谢!
Hello
Please let me know your adivce for output state of ADUM6401 at VDD1 off.
We think that output becomes high-impedance throguh below 2 pattern from the datasheet description.
Is it correct ?
1: ADuM6401 holds last logic state
2: output becomes…
Hi all,
I'm attempting to use the ADUM6401 to send 5V power over an isolation barrier but 3.3V logic as well. In the datasheet, it states that VDD1 and VDDL need to be connected together. Is it possible to have different logic and power supply voltage…
Hello!
I have a problem with ADuM6401. I use this part for isolation AD7793. I have it on SPI bus with other parts (LCD, EEPROM, another AD7793 (non-isolated), DAC).
And now about my problem. When ADuM6401 is connected to bus, there is a problem with…

LTM2887 might work for this application. The ADuM6401 may be another option. There are several options to look…
