This document describes the features and characteristics of the ADAV803 Rev. 0 audio codec for recordable DVD, including support for different sample rates, dynamic range, and digital interfaces.
The ADAV803 is a stereo audio codec designed for high-performance applications such as DVD and CD recorders. It integrates a stereo analog-to-digital converter (ADC), a stereo digital-to-analog converter (DAC), and a sample rate converter (SRC) on a single chip. The device supports asynchronous operation between the ADC and DAC and includes digital interfaces for record, playback, and auxiliary functions via S/PDIF and I2C-compatible serial ports.
The codec operates from a single 3.3 V analog power supply and a 3.3 V digital power supply (with an optional range of 3.0 V to 3.6 V). It is housed in a 64-lead LQFP package and is characterized for operation over a commercial temperature range of -40°C to +85°C. The document provides detailed specifications for the PGA, reference, ADC, SRC, DAC, PLL, and digital I/O sections.
