PRODUCT OVERVIEW
The AD1852 is a complete high performance single-chip stereo
digital audio playback system. It is comprised of a multibit sigma-
delta 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 frequen-
cies and 24 bits. It also is backwards compatible by supporting
50
μ
s/15
μ
s digital de-emphasis intended for “Redbook” compact
discs, as well as de-emphasis at 32 kHz and 48 kHz sample rate.
The AD1852 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
AD1852 can be configured in left-justified, I
2
S, 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 data
in MSB first, twos-complement format. The AD1852 oper-
ates 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
°
