Diodes is offering an 8-channel DAC and pre-amplifier chip for use in audio video receivers (AVR) and add-on sound cards.

Part of the Zetex Direct Digital Feedback Amplifier (DDFA) product line, the ZXCZM800 will deliver a dynamic range (DNR) as high as 126db.

In terms of DAC performance metrics, the ZXCZM800 offers a maximum resolution of 32 bits, meaning more headroom and less impact on performance with higher input audio data resolutions. 

Maximum sample rate is up to 192kHz and DNR in single ended operating mode is 120dB.  For distortion and noise, figures less than 0.001% are typical for single ended mode, less than 0.0004% in differential mode.

The ZXCZM800 DAC and pre-amplifier chip is supported by an 8-channel demonstration board, details of which will be made available for volume production DAC and preamplifier designs, and includes circuit diagrams, bill of materials and Gerber files.
