• ADuM2251 static output loading question

    Hello,

    I am using ADuM2250 as I2C isolator, in datasheet recommended operation conditions, it specifys static output loading of minimum 0.5mA, as attached. my question is whether or not it is necessary to maintain more than 0.5mA loading, and what will…

  • ADUM2251 Side2 Slave don't respond

    Hello,

    I have a design (see Appendix), that makes some communication problems.

    I have double-checked logic low level thershold and it is more than 0,9V since

    Vcc and Vcc-p is 5V.

    I have read this thread

  • RE: Does ADuM2251 contain magnetic or non-magnetic transformers?

    The ADuM2251 has no magnetic materials in the transformer.  It has high immunity to external magnetic fields.

  • RE: I want to set simple commands in the LMP91000 chip via I2C bus. Does anyone know of a simple USB device I can use?

    Hi TonyF,

    The LMP91000 appears to only have an I2C interface for programming. We'd recommend the ADuM1251 (2.5 kVrms) or ADuM2251 (5.0 kVrms) depending on the withstand voltage requirement for your system.

  • RE: Medical I2C Isolation Product?

    Hello,

    The ADuM2250 and ADuM2251 are certified to IEC 60601-1. The RI package with guaranteed 8mm creepage provides the highest approved working voltage.

    FYI, a summary of all digital isolator certifications can be found on the Safety and Regulatory…

  • ADuM1251 max permitted voltage for IEC 61010 reinforced

    I am getting a little confused. What is the maximum permited voltage under IEC
    61010 for reinforced insulation using this part?

     

    The ADuM2251 is the 5 kV version of that part (ADuM125x is 2.5 kV). The
    certification shows 300 V reinforced…
