The AD1833 is fully compatible with all known DVD formats,  
catering for up to 24-bit word lengths at sample rates of 48 kHz  
and 96 kHz on all six channels while supporting a 192 kHz  
sample rate on two channels. It also provides the “Redbook”  
standard 50 µs/15 µs digital de-emphasis filters at sample rates  
of 32 kHz, 44.1 kHz, and 48 kHz.  
APPLICATIONS  
DVD Video and Audio Players  
Home Theatre Systems  
Automotive Audio Systems  
Set-Top Boxes  
The AD1833 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 AD1833  
can be configured in left-justified, I2S, right-justified, or DSP  
serial port compatible modes. The AD1833 accepts serial audio  
data in MSB first, two’s complement format. While the AD1833  
can be operated from a single 5 V power supply, it also features  
a separate supply pin for its digital interface which allows the  
device to be interfaced to devices using 3.3 V power supplies.  
Digital Audio Effects Processors  
GENERAL DESCRIPTION  
The AD1833 is a complete, high-performance, single-chip, multi-  
channel, digital audio playback system. It features six audio  
playback channels each comprising a high-performance digital  
interpolation filter, a multibit sigma-delta modulator featuring  
Analog Devices patented technology and a continuous-time  
voltage-out analog DAC section. Other features include an on-chip  
clickless attenuator and mute capability, per channel, programmed  
through an SPI-compatible serial control port.  
It is fabricated on a single monolithic integrated circuit and is  
housed in a 48-lead LQFP package for operation over the tem-  
perature range –40°C to +85°C.
