LME49710 and LME49720 end of life

Why is TI ending production of the LME49710 and LME49720?  

I own a small boutique custom recording equipment company, and the majority of the income my business makes comes from two products I've designed which use these two opamps, not to mention a 3rd product which I was preparing to launch that is also based around these IC's.  This is going to force me to completely re-work my business plan for the next few years, as I'll have to re-design all of these products.  Is there a suitable alternative IC that TI offers, with the same performance characteristics as the LME49710 and 20, which will require as little re-design work as possible, and also offer me the same sonic quality?

In other words, is there (or will there be) a drop in replacement opamp that sounds the same?  If not, then I find that very upsetting.

  • Hi Dustin,

    Welcome to E2E, thanks for your interest in our products!,

    Unfortunately these devices got caught up in an unavoidable technology process-node end of life. fortunately we can support orders for the device through the LTB date of 28 Sept 16, and can ship product through 28 March 2017.

    Additionally, TI's OpAmp business has a huge portfolio of newer parts that you can select from.

    In the case of the LM49710, you may take a look to the OPA1611, and for the LM49720, OPA1602 may be an option. 

    Sorry for any inconvenience this causes.

    Best Regards,

    Hi Diego,
    Thanks for the quick reply! I'll give those opamps a try. Before I do, I have to ask if there is any chance of there being anything similar to the LME49710 and 20 that is available as PDIP? All my designs are old-school analog with through-hole pcb's.
    Thanks,
    -Dustin

    Hi Dustin,

    Maybe OPA227P will be a fit to replace the LM49710 and OPA2227P for the LM49720.

    Hmm, yeah the 2.3 V/us slew rate of the OPA227p is too slow by a factor of 10. I'll have to try the OPA1611 on a brown dog adaptor. Thanks for your help!

    What is the status of the LME49860? If the 36V LME49720 is EOL and the 44V LME49860 is not, then this isn't really a problem.

    What is the status of the LM4562? If the LM4562 is not EOL then the LME49720 really isn't either: They are the same part.

    Though the LME49710 single op amp has input bias-current cancellation it can sometimes be replaced with the higher bias current NJM5534.

    JRC are still committed to through-hole. TI needs to continue to support these in DIP.

    Why do the product pages continue to show the LME49710/720 as "active?"
  • In reply to Wayne Kirkwood:

    Mouser has all of them listed as EOL. However, they are the only site that does. Even TI doesn't have it listed as such on their site.
  • In reply to Dustin Creider:

    Mouser was kind enough to send me the EOL list they had received from TI. I'm not sure I can attach a pdf here so I've linked to it:

    www.proaudiodesignforum.com/.../ti_20150901004_09292015_eol.pdf

    This is the e-mail address in the cover letter.

    You will unfortunately find the LME49710 and LME49720 in the list along with the LM833, LM3915, LM3916 and a huge swath of linear product.

  • In reply to Diego Melendez:

    Are the LME49710 and LME49720 still being discontinued? Mouser no longer lists them as end of life.  Specifically the na/nopb version.
