TPA2029D1YZFR

Overview

The TPA2029D1YZFR is a single-channel mono Class-D audio amplifier manufactured by Texas Instruments. It delivers an output power of 3.2 W into a 4-ohm load with a total harmonic distortion plus noise of 1%. The device operates within a supply voltage range of 2.5 V to 5.5 V and functions across a temperature range of -40°C to +85°C. It utilizes a 9-pin DSBGA package for surface mount installation.

Feature Summary

• Integrates Smart Gain Automatic Gain Control and Dynamic Range Compression for optimized audio performance
• Class-D topology provides high efficiency in a compact footprint
• Includes protection mechanisms against short circuits and thermal overload

Applications

• Portable multimedia devices requiring efficient mono audio amplification
• Smart home speakers and voice assistants
• Industrial audio interfaces operating in wide temperature environments

Procurement Notes

Verify the specific suffix YZFR corresponds to the reel packaging configuration when ordering. Confirm that the application circuit supports the 2.5V to 5.5V supply range. Ensure the PCB layout accommodates the 9-DSBGA package dimensions. Validate component authenticity through authorized distribution channels to avoid counterfeit risks.

Selection Notes

Select this component when a mono Class-D solution with integrated AGC/DRC is required. Compare against the TPA2028D1 if lower quiescent current is prioritized over dynamic range control. Consider the TPA2039D1 for applications demanding lower THD+N specifications. Ensure the 4-ohm load impedance matches the target speaker requirements.

Part Context

This part belongs to the TPA2029D1 series of audio amplifiers. It shares the DSBGA-9 package form factor with other members like the TPA2028D1 and TPA2039D1. The series targets portable electronics where space constraints and audio quality are critical design factors.

Replacement Considerations

TPA2029D1YZFT is the tape-and-reel alternative to the standard reel version.
