ADuM6200为双通道数字隔离器，集成 isoPower隔离式DC-DC转换器，请教各位，我想测试ADUM6200中icoupler core的延迟时间，即tPHL和tPLH。
我的电路图连接如下图所示：
示波器显示输入和输出的波形如下图所示：
我想请问下，输出波形为什么是这样的，我在次级加的上拉电阻也没用，input加了bypass也没用，不知道是不是我的电路图有问题，还是说问题出现在我的pin 5或者6上呢？谢谢各位！
Hi,
I'm wondering whether or not there is any on-chip capacitance built into the ADuM6200 or does the IsoPower oscillator solely depend on the external decoupling?
If on-chip decoupling exists, can someone supply to me the value of the on-die/on…
N.B.:
I appreciate your posting with information about how to improve the ADuM5200 and ADuM6200 datasheets. I will try to include your suggestions when we next revise the datasheets. While we don't have an application note to address your concerns,…
Hello
Our customer will use ADuM6402.
So he requests VDE document.
We check the document of VDE 0884 on your web site .
Its document P.1 says "valid until 2014 12 31"
(I reffer attachment).
Uploaded document on web site has been expired…
Could you give me your advice what do below difference of value of clearance and creepage mean ?
VDE document downloaded on your web site says below.
Clearance: Over 8.5mm
Creepage: Over 8.5mm
(Please refer…
级联隔离栅以满足高爬电距离要求 by adiadmin
利用序列光耦合器建立双隔离栅会存在一些问题，因为数据完整性很差，而且没有一种紧凑和廉价的方式为两个隔离栅之间的接口提供电源。
随着高性能数字隔离器的问世，通过分层隔离器建立高压隔离栅现已成为一种可行的解决方案。由于新型电池和发电产业的快速扩张，我们需要具有很高工作电压的接口，还要求提供加强绝缘。例如，太阳能逆变器应用具有以下要求：
Working Voltage 800Vdc
工作电压 800Vdc
Pollution Degree 2
污染等级 2
Overvoltage …
