Product Description

GENERAL DESCRIPTION
The AD1852 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 AD1852 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.
