D2-92683-QR

Audio Special Purpose Overview

The D2-92683-QR is a fully integrated intelligent digital amplifier and sound processor from the D2-3 family. It functions as a System-on-Chip (SoC) combining a configurable multi-channel digital audio processor with Class-D amplifier control. The device features an embedded DSP for signal path processing, including equalization, dynamic range compression, mixing, and filtering. It supports high-resolution audio performance with SNR exceeding 110dB and THD+N below 0.01%. The component is housed in a 72-pin QFN package measuring 10.0 x 10.0 mm.

Audio Special Purpose Feature Summary

• Integrated configurable DSP engine supporting equalization, compression, mixing, and filtering via D2 Audio Customization GUI.
• Built-in PWM engine for programmable Class-D amplifier output control with internal noise shaping.
• Embedded asynchronous sample rate converter and dynamic level-dependent timing for high-fidelity audio.
• Graceful fault recovery mechanisms and support for multi-channel output configurations.

Audio Special Purpose Applications

• DTV and Blu-ray Soundbar systems
• Home Theater Systems and Home Theater in a Box (HTiB)
• Audio Video Receiver (AVR) units
• Multi-Channel Multi-Media (MM) Systems
• Powered speaker systems

Audio Special Purpose Procurement Notes

Verify the specific suffix 'T' indicates Reel carrier type packaging rather than Tube, as local fields may list generic packaging. Confirm Moisture Sensitivity Level (MSL) 3 compliance and lead-free RoHS status. Ensure compatibility with the D2 Audio Customization GUI v3 for configuration. Check assembly origin details such as Malaysia or Taiwan if required for supply chain documentation.

Audio Special Purpose Selection Notes

Select this model for applications requiring a complete SoC solution that merges DSP processing with Class-D amplification. The 72-pin variant offers identical performance to the 128-lead D2-3 family but in a smaller footprint. Ensure design requirements align with the supported input interfaces like I2S and S/PDIF. Consider the need for external Class-D power stages compatible with the internal PWM engine outputs.

Audio Special Purpose Part Context

This component belongs to the D2-3 family of digital audio processors. It shares identical performance characteristics with the larger 128-lead D2-3 devices, providing a flexible platform for cost-effective audio solutions. The D2-92683-QR specifically utilizes the 72-pin package configuration within this series.
