GENERAL DESCRIPTION 

The AD1852JRS is a complete, high performance, single-chip, stereo digital, audio playback system. It is comprised of a multibit, Σ-Δ modulator, digital interpolation filters, and analog output drive circuitry. Other features include an on-chip, stereo attenuator and mute, programmed through an SPI-compatible serial control port. The AD1852JRS is fully compatible with all known DVD formats, including 192 kHz, as well as 96 kHz sample frequencies and 24 bits. It is also backwards compatible by supporting 50 μs/15 μs digital de-emphasis intended for Red Book compact discs, as well as de-emphasis at 32 kHz and 48 kHz sample rate. 
The AD1852JRS has a very 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 AD1852JRS can be configured in left-justified, I2 S, right-justified, or DSP serial port compatible modes. It can support 16, 18, 20, and 24 bits in all modes. The AD1852JRS accepts serial audio data in MSB first, twos-complement format. The AD1852JRS 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 for operation over the 0°C to 70°C temperature range.
