Slightly OT: Tripath out of business?

[Mark Lanctot]

I was just googling around for information about Tripath (the company that makes the "Class T" 'digital' amplifiers) when I discovered something disquieting:

http://en.wikipedia.org/wiki/Class_T_amplifier

Despite superlative performance at low cost from the Class T approach, financial difficulties have caused Tripath to file for Chapter 11 bankruptcy protection on 8 February 2007.

Tripath used to sell the amplifiers as chips, or as chipsets, to be integrated into products by other companies in several countries.

The term "used to" seems to indicate they're no longer selling these and their website address is no longer valid:

http://www.tripath.com/

and Google can't find any alternatives.

Are they really gone? That would be a shame. A company making excellent, well-loved products in financial trouble. Reminds me of IMAX. :-(

All of Tripath's remaining assets and all of its circuit designs were purchased by Cirrus Logic. The Tripath chips are being made again. As of the last update I was able to get when asking what it would take to get a special order of the 25x2 chips, the issue is that at this time Cirrus has no interest in producing the low output power chips that DIY and low cost amp designs use. Low power for them now means 100 watts a channel. This is where the big market for large orders is anyway. There is a possible 50Wx4 in the future for use in the car stereo receiver market.
