TPA032D03DCA

Overview

The TPA032D03DCA is a 10-W mono Class-D audio power amplifier manufactured by Texas Instruments. It operates within an 8V to 14V supply voltage range and delivers maximum output power of 10W into a 4-ohm load. The device utilizes a 48-HTSSOP surface-mount package with a PowerTFSOP footprint (0.240 inch, 6.10mm width). It supports an operating temperature range from -40°C to 125°C TA.

Feature Summary

• Class-D topology for high-efficiency audio amplification
• Integrated thermal protection circuitry
• Supports differential input signals
• Includes pop-and-click suppression features

Applications

• Portable audio devices requiring efficient mono amplification
• Home theater systems utilizing single-channel speaker outputs
• Industrial audio equipment operating in wide temperature environments

Procurement Notes

Verify the specific suffix against official Texas Instruments documentation to confirm pinout compatibility and functional equivalence. Confirm RoHS compliance status and moisture sensitivity level prior to integration. Ensure the 48-HTSSOP package dimensions match the target PCB layout constraints.

Selection Notes

Select this component when a single-channel, high-power Class-D solution is required. Compare against the TPA032D01DCA for mono applications or the TPA032D04 series for stereo configurations. Evaluate the 48-pin form factor against available board space and thermal dissipation requirements.

Part Context

This part belongs to the TPA032 family of medium-power audio amplifiers. It shares architectural similarities with the TPA032D01DCA but is configured specifically for mono operation. The DCA suffix indicates the specific 48-HTSSOP package variant used in this product line.
