PRODUCT OVERVIEW
The ADAV803 is a stereo audio codec intended for applications
such as DVD or CD recorders that require high performance
and flexible, cost-effective playback and record functionality.
The ADAV803 features Analog Devices’ proprietary, high
performance converter cores to provide record (ADC), playback
(DAC), and format conversion (SRC) on a single chip. The
ADAV803 record channel features variable input gain to allow
for adjustment of recorded input levels and automatic level
control, followed by a high performance stereo ADC whose
digital output is sent to the record interface. The record channel
also features level detectors that can be used in feedback loops
to adjust input levels for optimum recording. The playback
channel features a high performance stereo DAC with
independent digital volume control.

The sample rate converter (SRC) provides high performance
sample rate conversion to allow inputs and outputs that require
different sample rates to be matched. The SRC input can be
selected from playback, auxiliary, DIR, or ADC (record). The
SRC output can be applied to the playback DAC, both main and
auxiliary record channels, and a DIT. Operation of the
ADAV803 is controlled via an I2C-compatible serial interface,
which allows the programming of individual control register
settings. The ADAV803 operates from a single analog 3.3 V
power supply and a digital power supply of 3.3 V with optional
digital interface range of 3.0 V to 3.6 V.
The part is housed in a 64-lead LQFP package and is character-
ized for operation over the commercial temperature range of
−40°C to +85°C.
