OPA2348: Op Amp on die

Part Number: OPA2348

We have a hearing aid application and wish to utilise the on-die version of the OPA2348 operational amplifier. We would like to open a dialog to commence incorporating the product. We are seeking guidance on how we can incorporate this into an initial product prototype schedule Q3 2020. There is potential to also incorporate on-die versions of other ultra-low current GP TI amplifiers in the same application.
Would you kindly put us in touch with a TI die/miniaturization FAE or other specialist?
Thanks

  • Please note that I initially lodged this case on TI Customer support case CS0233433 and in the reply was directed to lodge my query to this forum.

    Thanks

  • Hi Luke,

    Thanks for your inquiry.  They've directed you to the proper spot. 

    Just to be sure we are on the same page, can you explain what you mean by "on-die?"  Are you looking for something in a more die-sized package?  Or, are you trying to get a part literally printed onto another die?  Maybe you mean neither.

    I have just sent out a request to connect.  Please accept the request and we can then continue this conversation privately.

    Regards,

    Daniel

  • There is scant information about this that I've been able to acquire.

    On Digi-Key, the part OPA2348TDB1 is IC OPAMP GP 2 CIRCUIT DIE.

    Yes, for miniaturisation purposes were are investigating the die "package."

    Daniel, are you able to advise of which TI department you're a member?

    Thanks

    Luke

  • Hi Luke,

    Ok, I've understood that you're interested in purchasing the die directly.  I will put your case in front of my team members who are responsible for this type of request.

    I work for one of the amplifier teams itself.  In other words, I'm a member of the group of engineers that conceptualizes, develops, markets, and supports the parts.  The customer support team is another group of people in an entirely different portion of the company.

    Regards,

    Daniel

  • OK, thanks Daniel.

    The application also requires other low current TI GP op amps.  Down the track we could take a look at further integration.

    Our project team looks forward to hearing from your team.

    Regards

    Luke

  • Luke,

    I've let some of my colleagues know about your request.  We should have an idea of possibilities and timelines here rather soon.  I will reach out again as soon as I have an answer, which will probably be within 24 hours.

    If you're also interested in a low current TI amp, my team handles those as well.  You can post questions about those on e2e at any time and hear back from me or one of my teammates.  Out of curiosity, do you think you'd also be looking at chip-scale devices for the low-power parts?

    Regards,

    Daniel

  • It is a distinct possibility, pending review on the logistics about which your team will be providing further information.

    Some of the other amps are already BGA, so that should be fine for prototypes.  We'll review the miniaturisation aspects as the design matures.

  • Hi Luke,

    Sounds good.  I will send out an email here shortly to further discuss the opportunity.

    For the sake of book keeping, I will mark this thread as completed.  You can come back and comment again or open a new one if you would like.  If you provide the same part number on a new thread, my team will find you again.

    Regards,

    Daniel
