LM49350 - looks good, but is it recommended for new products?

Hi,

Anyone who is supporting LM49350 please? It seems TI doesn't like this NS part?? Come on, NS had many better analog/mix signal parts, isn't it why TI acquired it.

It would be sad to drop this part, but I may have to, as you guys don't even support it... sigh

Don,

Can you please help check this part? Thanks.

Best.

Have you looked at the AIC3212?

Hi, Frank,

Unfortunately, the resources to support the LM49350 have left the company.

As Dave mentions, the TLV320AIC3212 is a 100% fully supported device. Take a look and let us know what you think.

Thanks Don and Dave for your replies. I appreciate that.

TLV320AIC3212 may be a good "all-in-one" chip for some applications. Its specs look fine, and it has multiple audio inputs and outputs, but the combination of its ADC count and price may lose some advantage. 

It's sad that I have to start over and reevaluate solutions.

Hi, Frank,

LM49350 is a high run rate device for us, so we will not NRND it anytime soon. But, as I mentioned above, supporting it is a little bit tough for us. We will do our best to answer any questions you might have if you decide to keep using it.

Hi Don,

My major concern about this part is, does TI still keep the manufacturing line of this part, so that TI can continue producing this part? 

Another thing that worries me is, besides the difficulties of support, the evaluation board for this part is over $1000 (yes, crazy!), and obsoleted on Digikey. Engineering effort and cost may directly affect the run rate. Do you still or plan to provide the evaluation kit?

Also I noticed that there is a software application for LM49352, but not for LM49350.. Is it still available for LM49350?

- Yes it took me a while studying this chip, as I said it looks good. Luckily I'm still in early design phase.

I would also like to see this good chip to continue, at least say another 5 to 10 years. Can you also advise me TI's policy on its lifetime, and when it comes to the end of this chip? Thanks.

Frank
