Hi Friends, In this video I have explained the rise and fall of Tripath Technology which was operated by Mr. Adya S Tripathi. I have also done a small review of their Chip TA2024 in this video.

Class T was a registered trademark for a switching (class-D) audio amplifier, used for Tripath's amplifier technologies (patent filed on Jun 20, 1996). Similar designs have now been widely adopted by different manufacturers.
The control signals in Class T amplifiers may be computed using digital signal processing or fully analog techniques. Currently available implementations use a loop similar to a higher order Delta-Sigma (ΔΣ) (or sigma-delta) modulator, with an internal digital clock to control the sample comparator. The two key aspects of this topology are that (1), feedback is taken directly from the switching node rather than the filtered output, and (2), the higher order loop provides much higher loop gain at high audio frequencies than would be possible in a conventional single pole amplifier.
Financial difficulties caused Tripath to file for Chapter 11 bankruptcy protection on 8 February 2007. Tripath's stock and intellectual property were purchased later that year by Cirrus Logic.

Tripath used to sell the amplifiers as chips, or as chipsets, to be integrated into products by other companies in several countries. For example:
Sony, Panasonic and Blaupunkt use them in several car stereos and integrated home cinema systems
Apple Computer used them in their Power Mac G4 Cube, Power Mac G4 (Digital audio), eMac and iMac (Flat Panel) computers
Audio Research, an audio electronics company, formerly an exclusive tube circuit specialist, produced a Tripath-based audiophile amplifier.
Sonneteer, a British hifi company, analogue amplifier and technology specialists, manufactured the Bronte amplifier (1999),[2] based around a Tripath class-T module.
Bel Canto Design used them in their eVo range of amplifiers.
Virtue Audio used them in their ONE, TWO, and Sensation range of amplifiers from around 2008-2014.
Sonneteer, a British hifi company, analogue amplifier and technology specialists, manufactured under Sub Brand Bard Audio, the BardThree amplifier (2005),[3] based around a Tripath class-T chip and is/was known as the Plug Top or Rug Rat amp.
