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.
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.
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, I
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.
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.
