TPA2054D4AYZKR

Overview

The TPA2054D4AYZKR is a digital-input, Class-D audio power amplifier manufactured by Texas Instruments. It delivers 3W of continuous output power into a 4-ohm load with less than 1% total harmonic distortion plus noise at 5V supply voltage. The device operates from a single 2.5V to 5.5V supply and features integrated short-circuit protection and thermal shutdown. It utilizes a pulse-density modulation input interface for direct connection to digital audio sources.

Feature Summary

Digital input interface supporting pulse-density modulation for simplified system integration
High efficiency Class-D architecture reduces heat dissipation requirements
Integrated protection mechanisms including thermal shutdown and short-circuit current limiting

Applications

Portable media players
Mobile phones and smartphones
Personal digital assistants

Procurement Notes

Verify the exact suffix 'YZKR' against the manufacturer's official ordering information to ensure correct reel size and tape configuration. Confirm that the digital input voltage levels match your system's logic standards before procurement. Check for any specific environmental or RoHS compliance certifications required for your region.

Selection Notes

Select this component when a compact solution for low-power digital audio amplification is required. Ensure the application supports a single-supply operation within the 2.5V to 5.5V range. Verify that the PCB layout can accommodate the necessary decoupling capacitors for stable Class-D operation.

Part Context

This part belongs to Texas Instruments' TPA205x family of mono digital-input Class-D amplifiers. These devices are designed for battery-powered applications where space and power efficiency are critical constraints. The family shares similar architectural features but varies in packaging and specific electrical characteristics.

Replacement Considerations

Consult the official TI replacement guide for verified cross-references. Generic Class-D amplifiers may not support the same digital input protocol without additional interface circuitry.
