• RE: I'm looking for i2c isolation military/defence/avionic device.

    Hi hhj,

    How about the ADuM1250?

  • ADuM1250

    When I leave one side open (e.g. pins 1,2,3,4 or 5,6,7,8 not connected),

    can I assume that SDA and SCL of the other side are off (high impedance)?

  • ADUM1250

    Hi

    I have a question ADUM1250.

    Is it possible to turn communication ON / OFF by turning ON / OFF the power supply to VDD 1 with FET?

    Best Regards

  • Cascade ADUM1250 I2C 400kHz

    Can I cascade the ADUM1250 on a 400kHz I2C bus?

    MCU - ADUM1250 - I2C slave1 - ADUM1250 - I2C slave2 - ...

    If so, how many times?

    Thanks, Koen.

  • RE: How to use ADuM1250 with two isolated power supply 3.3V and 5V

    Hi Zeno, 

    It doesn't sound like there is anything wrong with what you have described. I'll just point out a few details of the ADuM1250...

    • I'll assume bypass caps are not shown for simplicity (It is important to have them and keep them very close…

  • RE: Is the ADuM1250 a drop in replacement for the ADum1251

    In general, yes the ADum1250 will drop right in to replace the ADuM1251.  It will not work the other way around though, the ADuM1251 cannot usually drop in for an ADuM1250.  The only difference between the ADuM1250 and ADuM1251 is that the ADuM1251 has…

  • ADuM1250 side1 logic level

    Hello,

    I would like to connect AD5254 and ADuM1250 side1.

    When I check the logic level.

    AD5254 input level threshold seems Vih>2.4V, Vil<0.8V.

    ADuM1250 output level seems 600mV<Vol<900mV???

    I couldn't understand ADuM1250 output logic…

  • Can a ADuM1250 be used to isolate a digital interface with a AD8557?

    I'd like to use a ADuM1250 to isolate a AD8557 digital instrument amp from the FPGA it's connected to. Is this possible or is the ADuM1250 interface only compatible with I2C devices?

  • RE: DRV10983 AND ADUM1250

    Hi whyzix, 

    First I want to point out that we have a video on how and why the levels on the ADuM1250 work here:

    How I2C Isolators Work

    So with the ADuM1250, the levels on Side1 and Side2 are different. Side2 is I2C compliant and Side1 is I2C compatible…

  • RE: ADM3260 ibis model

    Hi tkwanderson,

    There is not an ADM3260 IBIS model available. For an immediate work around, the ADuM1250 and ADuM5010 IBIS models.
