TPA032D02DCAR

Overview

The TPA032D02DCAR is a stereo medium-power Class-D audio amplifier manufactured by Texas Instruments. It delivers 10W per channel into a 4-ohm load. The device operates on a supply voltage ranging from 8V to 14V. It utilizes a 48-pin HTSSOP package and supports an operating temperature range of -40°C to 125°C.

Feature Summary

• Incorporates differential inputs for improved noise immunity in audio signal paths.
• Includes integrated depop circuitry to eliminate speaker popping during power transitions.
• Features thermal protection to safeguard the device against overheating conditions.

Applications

• Stereo audio systems requiring medium power output
• Professional audio equipment utilizing differential signaling
• Consumer electronics with strict thermal management requirements

Procurement Notes

Verify the specific suffix DCAR indicates the tape-and-reel packaging configuration when sourcing components. Confirm that the 48-HTSSOP footprint matches the target PCB design. Ensure the supply voltage range aligns with the system's power architecture before integration.

Selection Notes

Select this component for applications requiring stereo Class-D amplification with differential input support. Consider the 48-pin HTSSOP package constraints for layout planning. Evaluate thermal dissipation needs given the 125°C maximum junction temperature rating.

Part Context

This part belongs to the TPA032 family of audio amplifiers. Variants such as TPA032D01 offer mono configurations, while others may include headphone drivers. The TPA032 series targets medium-power stereo applications within the Texas Instruments portfolio.

Replacement Considerations

Direct substitutes include TPA032D02DCARG4, which shares identical electrical characteristics but may differ in environmental compliance markings. Verify pin compatibility and thermal performance when considering alternative packages within the same functional family.
