ADAV801ASTZ-REEL

Overview

The ADAV801ASTZ-REEL is a stereo audio codec manufactured by Analog Devices Inc., designed for high-performance recordable DVD and CD applications. It integrates a stereo ADC, stereo DAC, and sample rate converter (SRC) within a single 64-lead LQFP package. The device supports 24-bit resolution with dynamic ranges of 102 dB for the ADC and 101 dB for the DAC. It accommodates sample rates from 32 kHz to 192 kHz and includes an integrated S/PDIF receiver and transmitter. Power supplies operate at 3.0 V to 3.6 V, and the component functions reliably across a temperature range of -40°C to +85°C.

Feature Summary

• Integrates stereo analog-to-digital and digital-to-analog converters alongside a high-performance sample rate converter on a single chip.
• Includes built-in digital interface receiver and transmitter supporting S/PDIF standards for direct digital audio connectivity.
• Features programmable gain amplifiers with automatic level control capabilities to optimize recording signal levels dynamically.
• Provides flexible clock generation through PLL-based audio master clock generators compatible with various system requirements.

Applications

• DVD-recordable devices
• CD-R/W drives

Procurement Notes

Verify component authenticity through authorized distributors or official manufacturer channels. Confirm the specific REEL packaging suffix matches production requirements. Check for RoHS compliance status and ensure storage conditions adhere to moisture sensitivity level guidelines to prevent damage prior to assembly.

Selection Notes

Select this component when designing systems requiring simultaneous high-fidelity recording and playback with format conversion capabilities. Ensure the design supports the required 64-lead LQFP footprint and provides adequate thermal management for the specified operating temperature range. Verify that the host controller can interface via the SPI-compatible serial port for register configuration.

Part Context

This part belongs to the ADAV801 series of audio codecs from Analog Devices. It is specifically engineered for optical disc recording applications where precise sample rate matching between different digital sources is critical. The device consolidates multiple audio processing functions to reduce board space and simplify system architecture compared to discrete solutions.

Replacement Considerations

The ADAV803 is a documented variant within the same family offering similar functionality. Verify pin compatibility and register mapping before substitution. Consult official documentation to confirm if specific ordering suffixes alter electrical characteristics or package dimensions.
