• Understanding the ADA4091-4 Input protection circuitry

    I have a circuit design which has an op amp with +/-15V rails feeding into an ADA4091-4 on 0->3.3V. There is 9.4k between the 2 parts of the circuit. Is this sufficient to protect the 4091 in light of an over voltage condition, or will it fail immediately…

  • ADA4091-2



    I'm developing my circuit by using this RRIO dual op amp ADA4091-2.


    My input supply is a single supply of 18V and 20V. In my circuit i have used two per of this op amp ADA4091-2.


    I had read through the datasheet of ADA4091-2 the…

  • RE: ADA4091-2 Immunity Test Questions



    ADA4091-2/4 has two different ESD circuits for enhanced protection as shown on the DS rev. H page 15 figure 48. However, the test methods and results for these tests are not publised in the datasheet. But given that sophisticated input protection…

      I wanted to ask for clarification on the VS and HS signals with the ADV7619 in pass through mode.  i read the thread on this previously https://ez.analog.com/message/156902#156902 and it does say that the CP will be bypassed and the syncs remain…

  • ADV7627 RGB 4:4:4 Color Space Issue

    We are using the ADV7627.

    An error occurs when we have a source generating RGB 4:4:4. Output color is incorrect and exhibits lots of pink.  When the source is connected directly to the display everything looks just fine. BTW, auto-CSC doesn't seem to…
