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.
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.

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

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