Delivering high power quality audio with the efficiency of Class D

Class D architecture has been around for many years, but historically efficiency gains have been at the expense of audio quality. Now the advantages of Class D with sonic performance that truly rivals that of prestige linear amplifiers.

Premium digital performance
DDFA Amplifiers DDFA DACs Direct Digital Feedback Amplifier (DDFA™) technology digital input enables digital to analog conversion (DAC) and switching amplifier solutions capable of producing outstanding sound quality. DDFA describes the unique, exceptional performance of these multi-channel products when used as either closed loop digital amplifier chipsets or high quality digital preamplifiers and DAC’s.

Analog performance
Analog Input Amplifiers The ZXCD series controllers form the heart of quality analog input switching amplifiers. Combination of ZXCD devices with high performing discrete MOSFET based output stages provides the best performing solutions in subwoofer and full band applications.

Market sectors
Applications The proliferation of digital sources means that digital power amplifier technology is particularly well suited to specific market sectors. The benefits in quality audio performance, high efficiency and small size give clear advantages.

Technical resource

DAC and pre-amp brings cost and performance advantages to AVR and sound card design

Diodes Inc. has introduced an 8 channel DDFA™ DAC and pre-amplifier chip offering product designers the opportunity to reduce component costs and improve audio performance. The ZXCZM800 dramatically reduces circuit complexity, and will deliver a DNR as high as 126db.

In designs currently using multiple 2-channnel DACs, the ZXCZM800 offers the means to reduce component inventory and PCB size and improving sound quality.

The ZXCZM800 also offers the option of pre-amplifier DSP features such as integrated volume control and digital multiplexing to further enhance product features and performance.
