(ADuM128*)Supply current VS temp.

Hi !

Do you have any value for supply current with changing temperature?

At datasheet ,

I think this is 125deg spec.

Our customer wants to know that if they use ADuM128x with lower temperature ,

can they decrease the supply current?

Our customer are gona use ADuM128x lower in the temperature range of -40 to 85°C.

If you have any supply current test results with few temperature can you show me?

Best regards

  • Hi Joseph.

    Thank you for your answer.

    I understood that our customers would not be able to decrease the supply current.

    Our customer want to use the iCoupler with 1MBps.

    And also they want to reduce an emission noise.

    So, they want to use 2nd generation iCoupler or more newer.

    =>ADUM140

    But I think this will be trade off with the supply current.

    In any case I have to talk about this with my customer.

    Best regards.
