Offers Cost Reduction and Performance Enhancements for Audio/Video Receivers and Sound Card Designs
Diodes Incorporated, a leading global manufacturer and supplier of high-quality application specific standard products within the broad discrete and analog semiconductor markets, announced the release of an 8-channel DAC (digital-to-analog converter) and pre-amplifier chip. This new device offers designers of audio/video receivers (AVRs) and add-on sound cards the opportunity to improve audio performance, while also reducing costs.
As an addition to the Diodes’ Direct Digital Feedback Amplifier (DDFA™) product line, the ZXCZM800 dramatically reduces circuit complexity. In both consumer and professional audio product designs that currently use multiple quality 2-channel DACs to achieve mid- to high-level audio performance, the ZXCZM800 significantly reduces component count and printed circuit board (PCB) real estate. In high-performance differential mode, the DDFA product line delivers a dynamic range (DNR) up to 126dB. Additionally, Diodes’ solution provides equal and, oftentimes, improved sound quality of typical mid-range AVRs and sound cards that currently produce a DNR of 112dB. For designers looking to expand a product’s feature set, the ZXCZM800 also offers pre-amplifier digital signal processor (DSP) features, which can be easily programmed using an existing system host processor.
The ZXCZM800 DAC and pre-amplifier chip is supported by an 8-channel demonstration board, which is available for volume production DAC and pre-amplifier designs.
