DALLAS, USA: Diodes Inc. has released 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.
