This document describes the features and characteristics of the ADAV801 Rev. A audio codec. The codec supports 48 kHz/96 kHz sample rates and has a dynamic range of 102 dB. It includes a stereo analog-to-digital converter (ADC) and a stereo digital-to-analog converter (DAC) that support sample rates of 32 kHz/44.1 kHz/48 kHz/96 kHz/192 kHz and have a dynamic range of 101 dB. Additionally, it includes a stereo sample rate converter (SRC), digital interfaces, S/PDIF input and output, digital interface receiver and transmitter, as well as device control via an SPI-compatible serial port.
The ADAV801 audio codec integrates a 24‑bit stereo ADC, a 24‑bit stereo DAC, and a sample‑rate converter (SRC) on a single 64‑lead LQFP chip. It supports a wide range of sample rates (8 kHz‑192 kHz) and provides high dynamic range for both recording and playback. Control is performed via an SPI‑compatible serial interface and the device operates from a single 3.3 V analog supply with optional digital supply ranges.
The document includes detailed specifications, pin descriptions, timing diagrams, layout recommendations, and power‑down options. It also provides ordering information and mechanical dimensions for PCB designers and system integrators.
