This document introduces the features of Analog Devices ADAV801 Rev. A audio codec, including supported sample rate, dynamic range, interfaces, etc.
The ADAV801 audio codec integrates a high‑performance stereo ADC, DAC and sample‑rate converter on a single chip, targeting DVD and CD recorders. It supports multiple sample rates, offers automatic level control, and is programmable via an SPI‑compatible serial interface.
The device operates from a single 3.3 V analog and digital supply, is housed in a 64‑lead LQFP package, and is rated for commercial temperature ranges (‑40 °C to +85 °C). Detailed specifications cover dynamic range, crosstalk, power consumption, and timing parameters.
