Will there be a dual version ADA4627-1.

If so, that will be ADA4627-2.

I have been waiting (4 weeks) to have this question answered, please!

I need it for my headphone amplifier product, understand?

BTW, I am most willing to do free field testing if you will provide the ADA4627-2s

Thank you. See my web site at: www.goldpt.com

  • Bryan,

    I wish you would have gotten a name so I could track this down further.  Was it a local field office

    or an office in Norwood?   Which department?  That is certainly unacceptable behavior.

    I was the product line apps engineer for the ADA4627-1.  I'm in Central Apps now.  The design

    engineer (35 years experience) and the packaging engineer (25 years experience) looked at this.

    Maybe a 0-70C part would be possible, but we don't do those anymore.  The 4627 is on a very

    advanced D.I. process, so the die is very tiny and you don't get much heat out.

    As a side note, we did the AD8672 dual, then the AD8671 single, then the AD8674 quad.

    So when the Mil/Aero guys were going to do a space level version of the 8674, they noticed

    we had a junction temp problem.  So we had to issue a PCN and change the data sheet to

    change the 8674 to a more restricted temperature.  We added some calculations to the apps section

    to explain.
