NORWOOD, Mass.--Apogee Technology Inc. here today announced a joint development agreement with STMicroelectronics to apply an all-digital amplifier technology a new series of semiconductors that replace digital-to-analog converter (DAC) circuits in audio systems.
"This agreement further solidifies our relationship with ST and provides the framework to execute our DDX Direct Digital Amplification product development strategy," said David Meyers, chief operating officer at Apogee. In February, ST licensed Apogee's DDX technology.
Under the licensing agreement, the companies have already released a 4.1 channel DDX controller and two DDX power devices that provide up to 100 watts of high efficiency pure digital audio power, according to Apogee. The company said these chips meet a wide range of traditional consumer electronic products and are ideal for emerging high growth applications such as a DVD receiver that integrates six-channels of audio amplification.
