Hi,
I will have a check whether we have the plan to get the certifications, and for your second question you will find the answer in Table 21 below.
ADuM1440/ADuM1441/ADuM1442 have the default high output state if input is unpowered and ADuM1445/ADuM1446…
We have a problem with one of your isolators ADuM1447 where from the datasheets package drawing the cheepage distance for the part is 5.6mm (enaugh for our purpose) but in the VDE report its stated 5.3mm (does not comply to standard in our case). Where…

Hi,
I have design AD5421 based 4-20mA loop powered system. The schematic is attached. I see following problem:
1. The D_VDD always outputs 4.2V but datasheet says 3.3V but can have 5.5V overdrive.
2. If REG_OUT pin floating instead of tying to D_VDD…
ADuM1441是具有默认高电平输出和3/1通道方向性的微功耗、四通道数字隔离器，其基于ADI公司iCoupler
技术。（提供双通道产品）。 这些隔离器件结合了高速互补金属氧化物半导体(CMOS)与单片空芯变压器技术，可提供出色的性能特性，优于光耦器件和其它集成式耦合器，同时在现有的所有隔离产品中功耗最低。 ENX信号可用于禁用内部刷新，从而将总静态电流降低至不足1 µA。
ADuM1440/ADuM1441/ADuM1442/ADuM1445/ ADuM1446/ADuM1447系列四通道2…
All devices in the family contain a refresh circuit to guarantee dc correctness at power up. If no pulses are received on the secondary side of the transformer for approximately 200 µs, the input side is assumed to be unpowered or nonfunctional…
No, an input transition (high to low or low to high) is required to guarantee that the ADuM144X output state matches the input state.
The receiver watchdog times out after approximately 200 us.
