Hi,
I'm a DFAE in Japan. Our customers are trying to replace the Si8645 with the ADuM140E. Therefore, I am receiving the following two questions by him.
1. Input terminal hysteresis characteristic Vhys
2. Output impedance Zo
Both of the above specifications…
Hi Gudjon,
It would be generally expected that the latest generation of standard data isolators (of which ADuM140E is part) would have less emissions. The devices are designed with different architectures and output stages though.
There are many factors…
Hello
Our customer asks below question about ADuM140E because he will set enable pin to OPEN .
Please let me know your advice.
Question
Datasheet describes that EN pin of ADuM140E can be opne.
Does this contain internal pull-up resistor ?
If so, could…
I am looking for an isolator that operates with Vdd1=2.5V and Vdd2=3.3V. (Vdd1 side has 2.5V logic levels)
In the datasheets for ADuM1400 and 3480 I read that the output goes to a default state when no transitions occur on the input within 5us.
I want…
Hi !
I saw the datasheet about ADuM140.
For example , ADuM140D/E's supply current is this.
1)
I think this data is 50%-duty.
Is it correct…
Hi,
Beside isolation, can ADuM140 and ADuM 220 work as level shifter as well? For example VDD1 as 1.8V, VDD2 as 5V or 3.3V.
Thanks

以下供您参考：
ADuM140E系列可以兼容140D，您可以看一下ADuM140E1BRQZ，区别在于您现在使用的支持输入禁用使能，140E是支持输出禁用使能。
Thank you for your reply.
I like to confirm one more thing.
the customer said as follows.
Is this the same reason and can he fix this problem when he use ADuM140E or ADuM1440?
He supplied 3.3V between VDD2 and GND2.
when he measured the voltage between…
The following article shows the stack-up used for a six-layer board with multiple ADuM5411 devices, and may be a useful reference.
I'd also…
Hi Jiulu,
1. The "units" means different channels of different ADuM3440( eg: between ch1 of one ADuM3440 and ch2 of the other)
2. Yes, tPSKCD is the propagation delay between any two channels of a given ADuM3440.
3. tPSK and tPSKCD are tested…
