GENERAL DESCRIPTION
The AD1833A is a complete, high performance, single-chip,
multichannel, digital audio playback system. It features six audio
playback channels, each comprising a high performance digital
interpolation filter, a multibit S-D 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 for each channel, programmed
through an SPI compatible serial control port.

The AD1833A is fully compatible with all known DVD formats,
accommodating word lengths of up to 24 bits 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 stan-
dard 50 ms/15 ms digital de-emphasis filters at sample rates of
32 kHz, 44.1 kHz, and 48 kHz.
The AD1833A has a very flexible serial data input port that
allows glueless interconnection to a variety of ADCs, DSP chips,
AES/EBU receivers, and sample rate converters. It can be con-
figured in right-justified, left-justified, I2S, or DSP serial port
compatible modes. The AD1833A accepts serial audio data in MSB
first, twos complement format. The AD1833A can be operated
from a single 5 V power supply; it also features a separate supply
pin for its digital interface that allows it to be interfaced to devices
using 3.3 V power supplies.
The AD1833A is fabricated on a single monolithic integrated
circuit and is housed in a 48-lead LQFP package for operation
from –40∞C to +85∞C.

CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate
on the human body and test equipment and can discharge without detection. Although the AD1833A
features proprietary ESD protection circuitry, permanent damage may occur on devices subjected to
high energy electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid
performance degradation or loss of functionality.

De-emphasis
The AD1833A has a built-in de-emphasis filter that can be used
to decode CDs that have been encoded with the standard
Redbook 50 ms/15 ms emphasis response curve. Three curves are
available, one each for 32 kHz, 44.1 kHz, and 48 kHz sampling
rates. The filters may be selected by writing to Control Bits 9
and 8 in DAC Control Register 1 (see Table III).

Data Serial Interface Mode
The AD1833A’s serial data interface is designed to accept data
in a wide range of popular formats including I2S, right-justified
(RJ), left-justified (LJ), and flexible DSP modes. The L/RCLK
pin acts as the word clock (or frame sync) to indicate sample
interval boundaries. The BCLK defines the serial data rate
while the data is input on the SDIN1–SDIN3 pins. The serial
mode settings may be selected by writing to Control Bits 7
through 5 in the DAC Control Register 1 (see Table IV).

DAC Word Width
The AD1833A will accept input data in three separate word-
lengths—16 bits, 20 bits, and 24 bits. The word length may be
selected by writing to Control Bits 4 and 3 in DAC Control
Register 1 (see Table V).

Interpolator Mode
The AD1833A’s DAC interpolators can be operated in one of
three modes—8ϫ, 4ϫ, or 2ϫ— then correspond to 48 kHz, 96 kHz,
and 192 kHz modes, respectively(for IMCLK = 24.576 MHz). The
interpolator mode may be selected by writing to Control Bits 1
and 0 in DAC Control Register 1 (see Table VII).
