ADAV803ASTZ-REEL

Overview

The ADAV803ASTZ-REEL is a stereo audio codec designed for recordable DVD and CD applications. It integrates a stereo ADC with 102 dB dynamic range and a stereo DAC with 101 dB dynamic range, both supporting 24-bit resolution. The device includes a sample rate converter (SRC) with 140 dB dynamic range, operating from 8 kHz to 192 kHz. Digital interfaces include S/PDIF input/output, DIR, DIT, and I2C control. Power supplies operate at 3.0 V to 3.6 V. The component is housed in a 64-lead LQFP package.

Feature Summary

• Integrated stereo analog-to-digital and digital-to-analog converters with high dynamic range performance.
• Built-in sample rate converter enabling flexible matching of different input and output sampling frequencies.
• Supports asynchronous operation between the record and playback channels.
• Includes integrated S/PDIF receiver and transmitter for digital audio interface connectivity.

Applications

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

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm packaging type and environmental compliance. Confirm that the component meets all required electrical specifications for the target application before integration. Ensure compatibility with existing system power supply voltages and digital interface protocols.

Selection Notes

Select this component when designing systems requiring simultaneous high-performance recording and playback capabilities. The integrated SRC simplifies designs involving mixed sample rates. Verify that the 64-lead LQFP package fits the available PCB space and thermal requirements of the final assembly.

Part Context
