The AD1857/AD1858 are complete single-chip stereo digital audio playback components. They each comprise an advanced digital interpolation filter, a revolutionary "linearity-compensated" multibit sigma-delta () modulator with dither, a jitter-tolerant DAC, switched capacitor and continuous time analog filters and analog output drive circuitry. Other features include digital de-emphasis processing and mute. The AD1857/AD1858 support continuously variable sample rates with essentially linear phase response, and support 50/15 s digital de-emphasis intended for "Redbook" 44.1 kHz sample frequency playback from Compact Discs. The user must provide a master clock that is synchronous with the left/right clock at 256 or 384 times the intended sample frequency.
