TPA2054D4YZKR

Overview

The TPA2054D4YZKR is a stereo Class-D audio amplifier subsystem manufactured by Texas Instruments. It delivers 940 mW of output power per channel into a 32-ohm load. The device operates within a supply voltage range of 2.5 V to 5.5 V and maintains a total harmonic distortion plus noise of 0.01%. It features single-ended input and differential or single-ended output configurations. The component functions within an ambient temperature range of -40°C to +85°C and utilizes a DSBGA-25 package for surface mount installation.

Feature Summary

• Integrates stereo Class-D amplification with low distortion characteristics
• Supports flexible output configurations including differential and single-ended modes
• Operates efficiently across standard consumer audio supply voltages

Applications

• Audio subsystems in portable electronic devices
• Stereo audio playback circuits requiring compact form factors
• Low-power audio amplification in battery-operated equipment

Procurement Notes

Verify the specific suffix 'YZKR' against official Texas Instruments documentation to confirm reel packaging and tape-and-reel specifications. Ensure compatibility with required thermal management solutions for the DSBGA-25 package. Confirm RoHS compliance status through current manufacturer declarations before integration into final assemblies.

Selection Notes

Select this component when designing stereo audio paths requiring high efficiency and minimal external filtering. The integrated Class-D topology reduces heat dissipation compared to linear amplifiers. Verify that the 940 mW output rating meets the impedance requirements of the connected speakers or headphones.

Part Context

This part belongs to the TPA2054D4 series of audio amplifiers from Texas Instruments. The series focuses on providing high-quality audio reproduction in space-constrained applications. The YZKT variant represents the same core functionality but differs in packaging format, typically indicating cut-tape availability versus the reel configuration of the YZKR suffix.

Replacement Considerations

The TPA2054D4YZKT serves as a verified alternative offering identical electrical performance. Check pinout compatibility and thermal pad requirements when substituting between reel and cut-tape variants.
