26-Mar-01

Tripath Technology (NASDAQ: TRPH), creators of Digital Power Processing (DPPô) technology, announced that its digital audio amplifiers are providing high fidelity sound to Hitachi, Ltd.'s new 32-inch plasma screen televisions. Tripath's Class-Tô digital amplifier products produce less heat than traditional analog amplifiers; this efficient use of energy allowed Hitachi designers to create the world's first small size plasma display televisions, the W32-PD2100 and W32-PDH2100 with built in broadcast satellite digital receiver.The W32-PD2100 and W32-PDH2100 both use Tripath TA-2020 digital audio amplifiers and feature Class-T performance. Class-T architecture utilizes proprietary signal processing techniques combined with a switching mode approach to generate high fidelity sound without dissipating heat. Key to this performance are the 1-bit, Delta-Sigma modulation scheme and a 50MHz sampling frequency that ensure wide dynamic range and low distortion needed in high definition digital TV systems. The lack of significant heat dissipation contributed to the sleek design of these compact flat panel TV's.Both of Hitachi's 32-inch plasma screen televisions are targeted for the Japanese, U.S. and European markets. The first set, the W32-PD2100, is scheduled for release in April 2001.""Tripath's 1-bit digital audio amplifier enabled Hitachi to bring high quality sound in a compact 32-inch plasma TV,"" said Yoshiyuki Imoto, General Manager, Digital Media Systems Division, Hitachi, Ltd.""We're proud to add Hitachi to the list of premiere equipment manufactures that have taken advantage of Tripath's unique combination of high fidelity and power efficiency to produce innovative products like the world's first 32-inch plasma TV,"" said Neal Carney, Tripath's Vice President of Marketing.For more information about Tripath Technology, visit www.tripath.com.
