• adum1441

    Hi,

    I am puzzled.

    Fig 1 of the datasheet suggest there are 2 bi-directional channels and two one-way channels.

    Table 23 shows 4 on-way channels; 3 from left to right, 1 from right to left.

    Which ones are bidirectional, which ones are uni directional?

  • ADum1441 communication direction from CPU to ADC

    Hi,

    As per CN-0382 Circuit note AD7124 SPI communication input pins CS, SCLK & DIN are connected to Adum1441 logic input points VIA,VIB & VIC and  SPI communication output pins DOUT connected to Adum1441 logic output point VOD.

    But CN-0376  Circuit…

    你好，CN-0382文档，关于ADuM1441应用，在第二页原理图中是不是将ADuM1441输入与输出用反啦。谢谢

  • RE: My Eval board CN-0376 does not work when power (3.3V) is fed through PMOD connector. The SDP board is taken away, the PWW_SEL jumper set to PMOD. The SDO stays low whatever I try. My SPI works OK because with a self fabricated ADC7124 board it works...

    The maximum speed of the ADuM1441 is 2Mbps  according to the datasheet.

    Hi,

    Have you attached here the schematic? Yes, you can use ADUM1441 as this is also the recommended digital isolator for AD7124.

    Thanks,

    Hi,

    Thanks for your reply.

    Yes, Iam using the power from DVCC pin to power up the isolators and the HART modem AD5700.

    As per Current  calculation the total current taken by the isolators ADuM1441 will not exceed 3.15mA.

    I have attached the schematics…

    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…
