Abstract	A 24-bit 192-kHz sample-rate digital-to-analog converter (DAC) achieves 120-dB A-weighted dynamic range in the 20-kHz band, and consumes 310 mW with a 5-V power supply. A third-order five-bit /spl Delta//spl Sigma/ architecture optimized for high-end consumer audio has been developed and used. A switched-capacitor (SC) DAC combined with infinite-impulse response (IIR) and finite-impulse response (FIR) filters is employed to increase immunity to clock jitter, and reduce analog power. Partial-range dynamic element matching (DEM) enhances mismatch shaping with reduced circuit overhead. The 7.8-mm/sup 2/ chip fabricated in 0.5-/spl mu/ m CMOS integrates a stereo DAC and all functions required for DVD-audio playback.
