GENERAL DESCRIPTION
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, Inc. 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 an 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.
