FEATURES  
T he AD1857/AD1858 are complete single-chip stereo digital  
audio playback components. T hey 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. T he AD1857/AD1858  
support continuously variable sample rates with essentially  
linear phase response, and support 50/15 µs digital de-emphasis  
intended for “Redbook” 44.1 kHz sample frequency playback  
from Compact Discs. T he user must provide a master clock that  
is synchronous with the left/right clock at 256 or 384 times the

intended sample frequency.  
T he AD1857/AD1858 have a simple but very flexible serial data  
input port that allows for glueless interconnection to a variety of  
ADCs, DSP chips, AES/EBU receivers and sample rate con-  
verters. T he AD1857 serial data input port can be configured  
in either 16-bit, 18-bit or 20-bit left-justified or I2S-justified  
modes. T he AD1858 serial data input port can be configured in  
either 16-bit right-justified or DSP serial port compatible modes.  
T he AD1857/AD1858 accept serial audio data in MSB first,  
twos-complement format. A power-down mode is offered to  
minimize power consumption when the device is inactive. T he  
AD1857/AD1858 operate from a single +5 V power supply.  
T hey are fabricated on a single monolithic integrated circuit and  
housed in 20-pin SSOP packages for operation over the  
temperature range 0°C to +70°C.
