• ADUM2250 VDE 0884-10 Safety Limiting Values

    I am currently designing a product which will use the ADUM2250 to isolate across Live 230Vac mains and will need to comply with EN60065 as a Class1 product

    I am trying to asses what I need to do about the safety limiting vaues and it seems confusing,…

  • AduM2250 not working

    I am communicating over I2C between two PIC24FJ microcontrollers (one as master, one as slave) with the AduM2250 in between them.  My schematic is attached.  My software works fine when i communicate between the two microcontrollers without the AduM2250…

  • ADuM2250 I2C Isolator DC Power Supply voltage level

    I am using ADUM 2250 I2C 5KV rms Isolator in my design. The VDD1 = 3.0 V DC is connected to 1st Micro controller SCL and SDA pins and VDD2 = 3.3V DC connected to 2nd Micro controller isolated SCL and SDA pins. Is it ok to use VDD1 = 3.0 V DC and VDD2…

  • Is there a way to simulate the ADuM2250 in ADIsimPE ? It only appears to have an IBIS model.

    Original Question: Is there a way to simulate the ADuM2250 in ADIsimPE ? It only appears to have an IBIS model. by PaultW

    I would like to be able to simulate the currents expected to flow into an ADuM2250 under some possible fault conditions and evaluate…

  • About the spec of ADUM2250

    I have a question about input supply current spec.

    Does the spec change depending on data rate?

    if so what is the data rate for this current spec on data sheet(attached file)?

  • ADUM2250 Working Voltage & Regulation Questions

    I'm very new to insulation standards, so I have a few questions.

    What I'm pretty sure on is our box will need double or reinforced insulation.  We will most likely be using I2C and probably will insulate the rest of the circuit from our high voltage…

  • RE: Question of LTC4151 (I2C Isolation)

    Or can it be used as an ADUM2250?

    ADUM2250 seems to be simpler to use because it does not have power.

    Reply please.
