TPA0102PWP

Overview

The TPA0102PWP is a stereo audio power amplifier in a 24-pin PowerPAD (TSSOP) package. It delivers 1.5 W per channel into 4-ohm loads at 5 V and 600 mW per channel at 3.3 V. The device supports Bridge-Tied Load (BTL) and Single-Ended (SE) modes with an internal input MUX for switching between line and headphone inputs. Total Harmonic Distortion plus Noise (THD+N) is less than 0.05% at 1.5 W output. Supply current is under 10 mA in shutdown mode.

Feature Summary

• Stereo audio amplification with integrated input multiplexer
• Configurable Bridge-Tied Load or Single-Ended operation
• Thermally enhanced PowerPAD surface-mount package

Applications

• Notebook computer internal speaker drive
• Portable multimedia systems
• Small non-powered external speakers

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm exact package and temperature range specifications. Confirm component availability status as legacy products may have limited supply channels. Ensure compliance with RoHS directives relevant to the manufacturing date code.

Selection Notes

Select this component for designs requiring high-fidelity stereo amplification in space-constrained environments. The PowerPAD package provides thermal performance comparable to larger through-hole packages. Verify that the PCB layout supports the required thermal dissipation paths for the intended power levels.

Part Context

This part belongs to the TPA0102 series of linear audio power amplifiers manufactured by Texas Instruments. It serves as a direct upgrade path from older mono amplifier configurations, consolidating stereo speaker and headphone drive capabilities into a single integrated circuit solution.
