My original designing use 5V optocoupler to finish the isolation function, optocoupler output drive the MMBF170L mosfet at ON or OFF state with very low frequency.
Now, I feeling ADuM1200 chip also can finish the same function, the better thing is…
i want to know the suplly voltage of adum1200 and adum1201,if they can work on 5V and 1.8V.
What kind of inputs and outputs does the ADuM1200 have?
The ADuM1200/1201 / ADuM1400/1401/1402 functional block diagrams in the datasheet indicate Schmitt-trigger buffered inputs, however this is not reflected in the electrical characteristics specification section. I would like to use passive shoot…
We've been using the ADuM1200AR and 1201AR for a while now. They often produce a small glitch when the output side is already powered up and the input side power is ramping up or down.
I noticed the ADuM1280/1281 should be drop in replacements but…
I would like to know what difference between ADUM3200 and 1200.
These devices are almost same.
Are there any particular difference at the customer of view?
Thank you for your help as always.
I need to isolate and I2C bus and one side is 3.3V and the other is 5.0V.
Currently we already have the ADuM1200 and ADuM1201 devices in our component database.
Would i be able to use a combination of these devices instead of one ADuM1250…
SPI总线中，用ADuM1400和ADuM1200做总线隔离，GPIO口模拟SPI总线，ADuM1400和ADuM1200速度等级都是最高的（样机用，选的好一些），使用中发现LMPMISO 5V信号经ADuM1200转换为3.3V MISO后，信号异常，信号波形如下图
