D2-92633-LR

Audio Amplifiers Overview

The D2-92633-LR is a System on Chip (SoC) from the D2-3 family, functioning as an intelligent digital amplifier and sound processor. It integrates a configurable DSP for audio signal path processing, including equalization, dynamic range compression, mixing, and filtering, managed via the D2 Audio Customization GUI v3. The device features an integrated PWM engine supporting programmable multi-channel output configurations. It supports multiple audio inputs such as I2S, S/PDIF, HDA, and ADC, alongside outputs like PWM and I2S. The internal architecture includes noise shaping, an asynchronous sample rate converter, and high-resolution operation to support Class-D amplifiers with SNR >110dB and THD+N <0.01%.

Audio Amplifiers Procurement Notes

Verify the specific package type and lead configuration against the official datasheet before procurement. Confirm that the required software tools, specifically the D2 Audio Customization GUI v3, are available for system integration. Ensure compatibility with external Class-D power stages regarding voltage levels and fault recovery mechanisms. Check for any specific environmental or export classification requirements relevant to your region.

Audio Amplifiers Selection Notes

Select this component when a complete SoC solution combining DSP processing and amplifier control is required. It is suitable for designs needing high channel counts and flexible audio routing without separate discrete processors. Consider the D2-3 family variants if different pin counts or package sizes better fit the board layout constraints while maintaining identical core performance capabilities.

Audio Amplifiers Part Context

This device belongs to the D2-3 family of Digital Audio Processors, which also includes models like the D2-92683-QR. The family provides identical performance characteristics across different package configurations, offering flexibility for various form factors. These devices are designed to replace traditional discrete audio solutions by integrating processing and amplification control into a single chip, reducing system complexity and cost.

Audio Amplifiers Replacement Considerations

Direct replacements within the same family include other D2-3 series models such as D2-92683-QR, provided the pinout and package dimensions match the existing design. Verify that alternative parts maintain the same 72-pin QFN footprint if physical replacement is necessary without PCB redesign.
