• ADUM6404 ISOLATOR FOR RS422 APPLICATION

    Dear sir,

    I read the ADUM6404 digital isolator datasheet perfectly....For my application i want to use this IC for isolating the RS422 signals from one ground to another ground before going to RS422 line receiver.....

    So i want clear clarification about…

  • isolated ade9000 + adum6404

    Dear analog, 

    I'm creating a custom board with a power meter.  for security I'm creating different planes and connect the ade via an isolator. 

    For cost approach I decided to use an ADUM6404 that integrates isopwer so I can "move"  data…

  • ADuM6404

    Is there a spec for the digital inputs for minimum rise time allowable.  If the inputs are Schmitt trigger and don't require minimum rist time is there a value for the hysterisis voltage?

  • ADUM6404: Not starting internal DC/DC after short power interruption on two devices

    Hello

    In one running product (DC/DC converter) we have used the part ADUM6404A, which has now failed in operation in the 2nd unit in the field.

    The failure behaviur is the following:

    If the 5V input to the internal DC/DC converter (5VS_D) gets interrupted…

  • RE: Recommandations for fixing EMC problems caused by digital isolators ("isoPower" devices family)

    Hi Antoine:

    Judge from the noise frequency point, ADuM6404 should be the root for noise.  some application notes have been released to address the radiated emission issue with isopower technology built in, such as adding stitching capacitor or power beads…

  • ADUM4160 iCouplers EMI

    Hello, during EMI/radio test (spurious radiated emission) we noticed non-conforming results regarding autorised radio emission level for our PCB design. We did carefull design. 43dBuV/m is the criteria for Spurious around 700 to 800 MHz that is the problem…

  • RE: ADE9000 shield kit design

    Hello

    you could but you system performances would decrease

    ADuM6404 pin 15 (VISO) - you need 5V because ADP122 will use this value to power ADE9000 with 3.3V. This choise is linked to ADUM high noise at VISO pin compared to ADP.

    As a direct consequence…

    How about ADuM6404 parallel ?? does any concern there? I would like Pout more bigger

  • Output short on ADuM6400

    Hi,

    I am looking at producing a cable tester. So,effectively a cable loop up to 3 metres which may or may not have cable faults.

    I was planning on using  Isolators such as the AduM6400 and ADuM6404 to protect a microcontroller from output shorts . The…
