CSRA6220

Next Generation Qualcomm® DDFA™ Amplifier Technology

DDFA technology is founded on a patented digital modulation and feedback technique, which corrects the distorting influences present in all Class D switching amplifiers which would normally compromise performance. DDFA is designed to deliver the high power efficiency of a class D amplifier, with the fidelity of high end linear amplifiers.

Our next generation DDFA Digital Amplifier Technology is ideal for manufacturers who want to integrate superior amplifier performance in a low complexity, cost effective way. It also offers compatibility with today’s high resolution 384kHz digital audio sources.
