C-8 A 117-dB D-Range Current-Mode Multi-Bit Audio DAC for PCM and DSD Audio Playback

Document Thumbnail

A current-mode multibit DAC has been designed to meet the needs of high-end audio with a dynamic range of 117 dB and THD+N of 0.0004%. The device supports the 24-bit PCM audio format at sample rates ranging from 16 kHz to 192 kHz, which allows DVD-Audio playback. The architecture implemented in the device differs significantly from previous multibit sigma-delta modulators. The achievements of the new architecture compared to previous proposals are a significant improvement of level linearity of signal-to-noise ratio (SNR) and idle tones, which arise from element mismatching. This circuit-block configuration also provides FIR filtering for DSD (SACD) input data.:
