• ADUM5211 VDD2 lower than expected

    I'm using the ADUM5211 Isolater and ADA4528-2 Dual Op-Amp to make an isolated current loop.  My circuit is below.  Unfortunately, when I apply 5V to the 5V0 net and 0V to the nEN pin, the 5V0ISO net is 2.3V (I expected to get 5V).

    Is there anything obviously…

  • ADUM5211 ESD immunity

    What is the ESD immunity for the ADUM5211?

    We plan to test ± 8 kV contact discharge, ± 15 kV air discharge (network 150 pF/330 ohm)

    Thanks

  • Input / Output Voltages ADUM5211 (or 6211)

    Can these devices be used with the "input" voltage at 3.3V, with the "output" (isolated side) voltage at 5.0V ?

  • ADum5211 Isolator Input Current Question

    I am trying to determine much current the ADuM5211 will draw if it is operating at 1Mbps and also powering an isolated LED at 12mA.  Therefore, the isolator power section is supplying about 18mA of isolated current (Idd1=2.7mA and Idd2=2.9mA max at 1Mbps…

  • isopower ADUM521x soft start

    The datasheet for the ADUM5211 & ADuM5212 both mention "Soft Start" for the isolated supply voltage ramp up, but not provide and details characterizing the soft start.  Is there any information that characterizes the turn on time for the…

  • RE: ADuM5241 alternatives

    BBRR:

    You can look at the ADuM5211 which comes in the SSOP package which is smaller than the ADuM5201 and consumes less current than the ADuM5241.

  • RE: I need a simple circuit to convert ADum5241 iCoupler isolator I/O to 3.3 volt levels

    John:  We have a newer isoPower digital isolator that can run from 3.3V VDD on side 1 and 3.3V on the isolated side.  It is called the ADuM5211 and comes in the 20 lead SSOP package, which is smaller than the other isoPower devices that come in the 16 pin…
