The AD1852 is a complete, high performance, single-chip, stereodigital, audio playback system. It is comprised of a multibit, Σ-Δmodulator, digital interpolation filters, and analog output drivecircuitry. Other features include an on-chip, stereo attenuatorand mute, programmed through an SPI-compatible serial controlport. The AD1852 is fully compatible with all known DVDformats, including 192 kHz, as well as 96 kHz sample frequenciesand 24 bits. It is also backwards compatible by supporting50 μs/15 μs digital de-emphasis intended for Red Book compactdiscs, as well as de-emphasis at 32 kHz and 48 kHz sample rate.The AD1852 has a very simple, but very flexible, serial data inputport that allows for glueless interconnection to a variety of ADCs,DSP chips, AES/EBU receivers, and sample rate converters. TheAD1852 can be configured in left-justified, I2S, right-justified,or DSP serial port compatible modes. It can support 16, 18, 20,and 24 bits in all modes. The AD1852 accepts serial audio datain MSB first, twos-complement format. The AD1852 operatesfrom a single 5 V power supply. It is fabricated on a single,monolithic integrated circuit and is housed in a 28-lead SSOPfor operation over the 0°C to 70°C temperature range.
