TAS5729MDDCA

Overview

The TAS5729MDDCA is a Class-D audio amplifier manufactured by Texas Instruments, housed in an HTSSOP-48 package. It supports stereo or mono configurations with a maximum output power of 30W into a 4-ohm load at 16V supply. The device operates on a single power supply ranging from 4.5V to 26.4V and maintains a total harmonic distortion plus noise (THD+N) of 0.04%. It features a fixed gain of 30dB and functions within a temperature range of -25°C to +85°C.

Feature Summary

• Supports DirectPath topology for high-fidelity audio reproduction without output coupling capacitors.
• Integrates closed-loop I²S input interface for digital audio processing and synchronization.
• Includes built-in diagnostic capabilities for thermal protection and short-circuit detection.

Applications

• Smart home speakers
• Portable audio devices
• Automotive infotainment systems

Procurement Notes

Verify the specific suffix 'CA' against official datasheets to confirm package type and tape/reel specifications. Ensure compatibility with required operating voltage ranges and thermal management solutions for the intended application environment before finalizing procurement decisions.

Selection Notes

Select this component when a compact Class-D solution with integrated digital interfaces is required. Consider the HTSSOP-48 package constraints and thermal dissipation requirements relative to the 30W output capability. Verify that the system design accommodates the specified 4.5V to 26.4V supply range.

Part Context

This part belongs to the TAS5729MD series of audio amplifiers. It is designed for applications requiring high efficiency and low distortion. The series typically includes evaluation modules and related components for system development.

Replacement Considerations

Check for TAS5729MDDCAR as an alternative packaging option. Verify pin-to-pin compatibility and electrical specifications against current inventory or alternative suppliers if the primary part is unavailable.
