TPA3003D2PFBR

Overview

The TPA3003D2PFBR is a three-channel stereo Class-D audio power amplifier manufactured by Texas Instruments. It integrates volume control and operates within an ambient temperature range of -40°C to +85°C. The device utilizes a 48-pin Thin Quad Flatpack (TQFP) package for surface-mount installation. This component is designed for high-efficiency audio amplification applications requiring integrated digital or analog control interfaces.

Feature Summary

• Three-channel stereo Class-D architecture for efficient audio amplification
• Integrated volume control functionality
• Industrial operating temperature range capability

Applications

• Portable audio devices
• Home theater systems
• Computer multimedia speakers

Procurement Notes

Verify the specific suffix 'R' indicates reel packaging configuration against official datasheets. Confirm pinout compatibility with existing PCB footprints. Ensure thermal management requirements align with the TQFP-48 package limitations in the target application environment.

Selection Notes

Select this component when a three-channel stereo output is required alongside integrated volume adjustment capabilities. Consider the TQFP-48 package constraints regarding board space and thermal dissipation. Verify interface compatibility for volume control signals against the system microcontroller or audio source.

Part Context

This part belongs to the TPA3003 family of audio power amplifiers from Texas Instruments. It shares architectural similarities with other members like the TPA3003D2PFB, differing primarily in packaging or tape-and-reel specifications. The series focuses on delivering high-fidelity audio with reduced external component counts.

Replacement Considerations

The TPA3003D2PFB is a documented equivalent variant within the same product family. Verify functional equivalence and pin compatibility before substitution.
