TPA032D02DCAG4

Overview

The TPA032D02DCAG4 is a monolithic stereo Class-D audio amplifier from Texas Instruments. It operates on an 8 V to 14 V supply and delivers up to 10 W continuous average power per channel into a 4-Ω load at 0.5% THD+N from a 12-V source. The device utilizes bridge-tied load (BTL) configuration, eliminating external output coupling capacitors. It features a thermally enhanced 48-pin PowerPAD TSSOP surface-mount package.

Feature Summary

• Extremely efficient Class-D operation using high-speed power DMOS transistors for analog signal replication.
• Integrated chip-level shutdown control significantly reduces total supply current for battery-powered applications.
• Built-in thermal and under-voltage protection circuitry enhances device reliability during fault conditions.
• High switching frequency design allows for small output filter components while maintaining low distortion.

Applications

• Battery-powered stereo audio systems
• Bridge-tied load speaker configurations
• High-fidelity audio frequency range reproduction

Procurement Notes

Verify the G4 suffix indicates lead-free compliance against the manufacturer's specific ordering information. Confirm the DCA package designation matches the required 48-pin PowerPAD TSSOP footprint. Ensure the component meets RoHS standards if required by your assembly process. Cross-reference the datasheet revision date with your design timeline.

Selection Notes

Select this component when a stereo Class-D solution is required for 12-V systems. It is suitable for designs needing BTL output without large coupling capacitors. Consider the thermal requirements of the PowerPAD package for heat dissipation. Verify that the differential input interface aligns with your signal source capabilities.

Part Context

This part belongs to the TPA032 family of audio amplifiers. It is designed for high-efficiency stereo audio applications. The device integrates charge pump and gate drive circuits. It supports both left and right channel operations simultaneously.

Replacement Considerations

TPA032D02DCA is the standard tape and reel variant of this component. Check for availability of the non-G4 version if lead-free specifications are not mandatory.
