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 (åD) 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 ms 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.
The 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 converters. The AD1857 serial data input port can be configured in either 16-bit, 18-bit or 20-bit left-justified or I2S-justified modes. The AD1858 serial data input port can be configured in either 16-bit right-justified or DSP serial port compatible modes.
The 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. The AD1857/AD1858 operate from a single +5 V power supply.
They 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.
