AD1853

The AD1853 is a complete high performance single-chip stereo digital audio playback system. It is comprised of a high performance digital interpolation filter, a multibit sigma-delta modulator, and a continuous-time current-out analog DAC section. Other features include an on-chip clickless stereo attenuator and mute capability, programmed through an SPIcompatible serial control port. The AD1853 is fully compatible with all known DVD formats and supports 48 kHz, 96 kHz and 192 kHz sample rates with up to 24 bits word lengths. It also provides the "Redbook" standard 50 s/15 s digital de-emphasis filters at sample rates of 32 kHz, 44.1 kHz and 48 kHz.

The AD1853 has a 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 AD1853 can be configured in left-justified, I2S, right-justified, or DSP serial port compatible modes. The AD1853 accepts serial audio data in MSB first, twos complement format.

The AD1853 operates from a single +5 V power supply. It is fabricated on a single monolithic integrated circuit and is housed in a 28-lead SSOP package for operation over the temperature range 0°C to +70°C.
