    Hi, Bohdan,

    That is pretty old, I am afraid we might not have much information on it almost ten years later.

    Is there something you're specifically looking for?

    From time to time I cooperate with hospital audiology department. Older patients needs more powerful output with bigger battery. I was surprised that I have found only one analog device - Amiga from Siemens. Now I am looking for components and resource for it( strip of code). If I am satisfied I will set business plan for it.

    For the first time I am interested in TAS3204 DSP (but where PurePath Studio come from?), PGA2505 and suitable microphone(MEMS). I did not find how to choose suitable microphone.

    That is  all.

    Dear Dan

    I am developing a new hearing aid product.

    Can Texas supply the DSP chip and associated software?

    Many thanks

    Hi, Alan.

    As I mentioned above, this is quite old, and we don't have any info around here.

    I saw you posted in the C5x group. Hopefully someone there can help you out.
