TAS2555YZT

Overview

The TAS2555YZT is a digital input Class-D audio amplifier manufactured by Texas Instruments. It delivers up to 10W of continuous output power into an 8-ohm load and supports 4-ohm configurations. The device operates within a supply voltage range of 4.5V to 5.5V. Key electrical parameters include a total harmonic distortion plus noise (THD+N) of 0.006% at 1kHz, ensuring high-fidelity audio reproduction. It features integrated digital signal processing for dynamic range compression and equalization.

Feature Summary

• Integrates advanced digital signal processing capabilities including dynamic range compression and parametric equalization for optimized audio performance.
• Supports direct digital audio interfaces compatible with standard protocols such as I2S and TDM for seamless system integration.
• Includes comprehensive protection mechanisms against thermal overload, short circuits, and over-current conditions to ensure operational reliability.

Applications

• Smart home speakers and voice-controlled audio devices
• Portable Bluetooth speakers and wireless audio systems
• Automotive infotainment speaker modules

Procurement Notes

Verify the specific suffix YZT against official Texas Instruments documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with required digital audio interface standards before procurement. Cross-reference the manufacturer part number with authorized distributors to validate authenticity and current production status.

Selection Notes

Select this component when high-efficiency Class-D amplification with integrated DSP is required for mono audio applications. Consider the 10W output capability and low THD+N for premium sound quality needs. Evaluate the 4.5V to 5.5V operating range against the system power supply architecture. Verify that the digital interface requirements match the host processor's audio output capabilities.

Part Context

The TAS2555 belongs to Texas Instruments' family of digital input Class-D audio amplifiers designed for portable and fixed audio applications. It complements other models like the TAS2553 and TAS2557 by offering higher power output and enhanced DSP features. This series targets markets requiring compact, high-performance audio solutions with minimal external components.

Replacement Considerations

Consult official substitution guides for pin-compatible alternatives. Verify functional equivalence regarding output power, interface compatibility, and DSP feature sets before replacing.
