About the Company:

DPP® is a revolutionary technology with applications in a wide range of markets, including audio systems, high-speed networking and wireless communication.

In the audio arena, DPP® has given rise to a new class of true digital audio amplifiers, known as Class-T®. Our technology provides a combination of fidelity, power efficiency and economy far superior to the Class-A, -AB and -D amplifiers prevalent in current- generation audio. Tripath provides audio amplifier solutions to manufacturers of professional, home, car and PC sound systems.

In the area of high-speed networking, Tripath is using our expertise in power amplification to develop integrated silicon solutions for the DSL market. Our product features will enable DSL providers to increase port density and reduce energy costs. Within the wireless market, we are developing RF power amplifier solutions for cellular phones.

With our Digital Power Processing technology, Tripath is uniquely positioned to change the way power is processed.




Advances in semiconductor technology have enabled a digital revolution and spawned products that entertain us and improve our productivity. From CD players to digital high definition TV; from the PC, through optical networks, to the Internet and wireless telephones, digital electronics and signal processing has been the core enabling technology that brings the performance and cost for mass adoption.
Tripath now extends this digital revolution to the final frontier – the power devices that drive the human interfaces and communication networks. Using its proprietary Digital Power Processing technology, Tripath is combining the modern advances in digital signal processing with the power semiconductor technology to achieve a new level of performance and efficiency for amplifier and related products. The products Tripath will create with this new technology will enable entirely new classes of products and new levels of performance for existing products. More specifically, Tripath is engaged in applying this technology to audio systems, high-speed networking and wireless communications.

Audio

In Audio, Tripath is enabling personal computers to have home theater quality sound systems. In home and car sound systems, Tripath technology is enabling systems with more power in smaller, lighter configurations. Tripath has used its Digital Power Processing technology to create a new breed of digital audio amplifiers referred to as Class-T® amplifiers.

Class-T® digital amplifiers provide the audio fidelity of traditional linear (Class-A/B) amplifiers with more than twice the power efficiency of these devices. This leads to higher levels of integration and smaller packages at the semiconductor level. At the system level, these advantages reduce the size of power supplies and heat sinks and significantly reduce the heat management challenges of today's dense, complex electronic systems. While pulse width modulated (PWM) switching amplifiers (Class-D) can also achieve similar power advantages, none have been able to do so without a significant compromise in audio fidelity. Hence Tripath?s new designation, the Class-T® digital amplifier the new standard in audio performance and power efficiency. For more details on Tripath's Class-T® technology you can download the white paper below.

Communications
TLD401X Data Sheet

Today's high-speed wire line and wireless networks have similar requirements for amplifiers with low signal distortion while also being very efficient in power consumption. The ability for next generation cell phones and wireless products to carry voice and high-speed data require power amplifiers that are low noise and low distortion while simultaneously extending talk time and battery life. Tripath has R&D programs aimed at applying our Digital Power Processing technology to these important applications.

Another communications application that Tripath is targeting its technology for is Digital Subscriber Line (DSL). Specifically, Tripath is developing DSL line drivers that significantly lower the power consumption of DSL line cards in central office equipment. This allows more lines per card with less power and heat management issues, all critical considerations in this rapidly growing market.

Tripath intends to continue to innovate its Digital Power Processing technology and apply it to high volume applications that require high performance and low power signal amplification.




Tripath's Digital Power Processing technology will revolutionize the way we communicate. From Audio to DSL to Wireless Communication products, we will help make systems smaller, lighter and more powerful


Tripath has developed a family of highly efficient, switching power amplifiers for the audio market. These markets include: Consumer Audio such as home stereo, home theater, set top box, Web-based digital audio systems and gaming systems; Computer Audio for external powered speakers, add-in card for driving passive speakers and mother-board based solutions to drive passive speakers; Automotive Audio including after-market trunk full band amplifiers and subwoofers and in-dash head unit amplfiers.


Our DSL line drivers will allow service providers to increase the number of subscriber lines, their reach and signal speed without modification to existing infrastructure.


Implementation of our Digital Power Processing techniques in the RF power amplifier arena will yield longer battery life and longer talk time for cellular phone users.
