ADAV803 is an audio codec designed specifically for recordable DVD, supporting 48kHz/96kHz sampling rate, 102dB dynamic range, single-ended input, automatic level control.
The ADAV803 is a stereo audio codec intended for DVD and CD recorders, providing high‑performance ADC, DAC, and sample‑rate conversion on a single chip. It operates from a single 3.3 V analog supply and includes I²C‑compatible control, S/PDIF interfaces, and a PLL for clock generation.
The document contains functional block diagrams, detailed pin descriptions, electrical specifications, timing data, and layout recommendations to help designers achieve optimal performance in mixed‑signal PCB designs.
