TAS2563: Replacing the TAS2563RPPT in an existing design due to part out of stock

Part Number: TAS2563
Other Parts Discussed in Thread: TAS2559, TAS5722L, TAS2557, TPA3137D2, TPA3144D2, , TAS2110, TAS2562, TAS2764, TAS2780, TAS2781

Dear all,

 

our question was redirected by Vivian from the Customer Support Center Ticket System to this forum.

 

We currently use the TAS2563RPPT in a medical electric device and need to find a replacement with similar or "better" specs. In a first run we went for the TAS2559, ordered a first batch of 3000 units and evaluated. During project planning for the changes it turns out to be more difficult to integrated and produce than expected. Therefore, we would broaden the approach and explain the situation and possible choices to this forum.

 

Medical Electric Device with Bluetooth Module

mono speaker 5 Watts with 4 or 8 Ohm (both in stock)

battery voltage 3.7 V (step up preferably included in amplifier)

 

We have looked at a number of possible options from the TI portfolio and identified the TAS2559 as best replacement. Would you please give me some thoughts on the BEST SUITABLE and AVAILABLE parts:

TAS2559

TAS5722L

TAS2557

TPA3137D2

TPA3144D2

I am looking forward to your feedback.

 

Best Regards,

  • Hi Tim,

    Does you application require the Smart Amp algorithm? Some of the devices you mentioned have this feature and some don't.
    I'll add some options below:

    • TAS2110 - This is similar to TAS2563 (QFN version) but without IV-sense nor integrated smart amp algorithm. However it features the same integrated boost
    • TAS2562 - This is similar to TAS2563 (WCSP version) but without integrated smart amp algorithm, it only includes IV-sense feedback. It also features the same integrated boost
    • TAS2764 - This device is a higher power IV-sense capable amplifier. It features Y-Bridge architecture at the Class-D supply for improved efficiency
    • TAS2780 - Similar to TAS2764 but rated for higher voltage/power
    • TAS2781 - This is the latest smart amp integrated device rated for higher power, it does not feature integrated boost but it includes Class-H controller (Hybrid-Pro) for external boost as well as Y-Bridge architecture

  • Hi Ivan,

    for us it is important, that the components are readily available as we are currently running short in parts, even if we do really moderate quantities (up to 3000 a year).

    From your list I would highlight the TAS2562 and discuss with our devlopers.

    They chose the TAS2559 as a similar option, but you do not have it in your list. Could you tell, why you did not select it?

    Best Regards,

    Tim

  • Dear Ivan,

    I have feedback for mour devolopers.

    We use the digital Audio Tuning Option and they told me, that TAS2562 has been reviewed but was no alternative.

    As in my other reply: Do you think the TAS2559 is a siutable replacement?

    Best Regards,

    Tim

  • Hi TIm,

    TAS2559 is a previous version of the smart amp, so it includes the protection algorithm and would make it suitable. There are some differences in the features though, you may check these two devices in PPC3 to get an idea of what you get and loose between these two versions.

  • Dear Ivan,

    we got an Evalboard a few weeks back and found out, that it should be basically suitable for our purpose. Since than we learned that the production of PCBA with the different footprint will be a little more difficult. Nevertheless, we keep evaluating. I was just hopeing to find some other alternative that might save us some time redesigning the PCB. 

    Looking at it from this perspective. Do you see any other TAS2563 and TAS2559 alternatives?

    Additionally, we just learned last week that there still some TAS2563 in inventory and I am hopeing to buy some of these, a the redesign for the older and in our case newer TAS2559 takes longer than expected.

    Finally, is there a way to place an order for TAS2563 for the upcoming production in Q1/23 before there is inventory a available?

  • Hi Tim,

    I think we've covered basically all smart amp related devices in this thread already. there is no direct pin to pin replacement, I understand changing your design both on hardware and software side would take time.

    I don't really have further information about ordering units in advance, you may need to contact your local sales office for that purpose.

  • Dear Ivan,

    thank you for your support. I will reach out to TI-Germany in Eschborn, but I would also kindly ask to put me in touch with someone from the global sales team, because last time we ordered directly from the TI-global shop.

    Best Regards,

    Tim

  • HI Tim,

    I'll check how we can route your request, this is not common for Apps team support.

  • Hi Tim,

    Please wait until our audio experts have commented to continue the thread. Thank you for your patience

  • Hi Tim,

    I may reach out over private message next week after getting some feedback.
