[QUOTE="EFFENDI, post: 536667, member: 555674"] Yeah that CD-case sized one made by Xtant. (Waste of money in my opinion). Yes I was off with that date, based on some quick googling, it looks like the first Tripath chips were starting to be integrated into car amplifiers around 1998. The TA2022 which is used in car audio applications consists of three main operational blocks, the signal processor, MOSFET driver, and power MOSFETs. You are absolutely right, I neglected to mention that the only digital component is the signal processor, which operates from a 5V CMOS. Of course the power amplification components are still analog. More info at [URL="http://www.tripath.com/audio.htm"]www.tripath.com/audio.htm[/URL] Now if they could only increase power output levels, and lower costs, we'd all be swithing to Class T amplifiers.
