TPA032D02DCA

Overview

The TPA032D02DCA is a stereo Class-D audio power amplifier manufactured by Texas Instruments. It delivers 10W of output power per channel into a 4-ohm load. The device operates on a supply voltage range of 8V to 14V and utilizes a 48-HTSSOP surface-mount package. Key electrical specifications include an operating temperature range from -40°C to 125°C (TA). The component integrates differential inputs, mute functionality, shutdown control, depop circuitry, and thermal protection mechanisms.

Feature Summary

• Stereo Class-D architecture for high-efficiency audio amplification
• Integrated thermal protection and pop-noise suppression
• Supports differential input signals with mute and shutdown controls

Applications

• Portable media players
• Desktop speakers
• Home theater systems

Procurement Notes

Verify the exact suffix DCA to confirm the 48-HTSSOP package variant. Confirm RoHS3 compliance status as required by your assembly process. Check current availability as this specific part number may be subject to end-of-life or discontinuation notices from the manufacturer. Ensure the supplier provides valid traceability documentation for quality assurance purposes.

Selection Notes

Select this component when a stereo configuration is required rather than the mono TPA032D01DCA variant. Consider the 48-pin HTSSOP footprint for PCB layout constraints. Evaluate the 8V to 14V supply requirement against your system's power rails. Verify that the 10W per channel output matches the speaker impedance and sensitivity specifications of the target application.

Part Context

This device belongs to the TPA032 family of medium-power Class-D audio amplifiers. It shares core architectural features with other variants in the series but differs in channel configuration and packaging options. The TPA032D02DCA specifically addresses stereo applications requiring compact form factors and integrated protection features for consumer electronics.

Replacement Considerations

The TPA032D02DCAG4 is a verified lead-free replacement variant within the same product family. Other TPA032 series components may offer different channel counts or package types.
