I have a customer that is looking for a digital isolater, 2 channel, 1 input and 1 output.

- Powered from 5V and 3.3V

- The working voltage must be at least 1200VDC.

- It must support a UL creep-age and clearance of the same 1200VDC, possibly with…

ADuM3200/ADuM3201 Datasheet Rev. F: Table 27 states Minimum Internal Gap (Internal Clearance) of 0.017 mm.  For a device claiming 1 minute withstand tolerance of 2.5 kVac, this would suggest to me a peak dielectric strength for the insulator in the order…

For MTBF calculations in accordance with MIL_HDBK_217F, I need the number of transistors (or MTBF/FIT) for the following devices:

ADuM3200

ADuM3201

ADR395

ADM485

Where it's possible to find this data? Can anyone help me?

Thanks

Giova…

Hello,

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.

Best regards,

Sofy

单片机 IO 隔离输出：电路摘要如图一：

每一边的 VDD对GND 都就近 1cm内加有 1uF高频电容。

同样的测量环境；同样的逻辑分析仪：

在 ADuM3200 的输入 时间标尺 放大到 10nS 无毛刺 。

可 ADuM3200 的输出 却总是 存在 10nS 到20nS 的毛刺。

急求 AD 公司 技术专家 给予 解答 ，万分感谢 。。急。。
