TPA3007D1PW

Overview

The TPA3007D1PW is a mono bridge-tied load (BTL) Class-D audio power amplifier manufactured by Texas Instruments. It operates within an 8V to 18V supply voltage range and delivers up to 6.5W of continuous output power into an 8-ohm load. The device utilizes a 24-pin Thin Shrink Small-Outline Package (TSSOP). Key electrical characteristics include a total harmonic distortion plus noise (THD+N) of less than 0.2% at 4W output with a 12V supply, and an efficiency exceeding 85% under typical operating conditions.

Feature Summary

• High-efficiency Class-D architecture eliminates the need for external heat sinks in standard applications.
• Filter-free design capability using only a ferrite bead to reduce electromagnetic interference.
• Configurable gain settings via dedicated input terminals to match various source requirements.
• Integrated depop circuitry minimizes audible popping during power-up and shutdown cycles.

Applications

• Powered speaker systems
• Active loudspeaker arrays
• Audio amplification modules

Procurement Notes

Verify the specific suffix against official documentation, as package variations exist within the product family. Confirm current lifecycle status prior to integration, as availability may be limited. Ensure the selected variant matches the required thermal and pinout specifications for the target PCB layout.

Selection Notes

Select this component for designs requiring high power density without complex filtering networks. Evaluate the thermal performance based on the specific enclosure constraints, as the filter-free operation relies on efficient heat dissipation through the package. Verify that the supply voltage remains within the specified operational limits to maintain optimal efficiency and signal integrity.

Part Context

This part belongs to the TPA3007D1 series of single-channel audio amplifiers. It is designed for applications where space and cost are critical factors. The device integrates protection features such as thermal shutdown and short-circuit protection to ensure robust operation in consumer audio environments.

Replacement Considerations

Consult official substitution guides for compatible alternatives. Verify pin compatibility and thermal characteristics when considering cross-references from other manufacturers or different product lines within the same portfolio.
