TPA3101D2PHPR

Overview

The TPA3101D2PHPR is a stereo Class-D audio power amplifier manufactured by Texas Instruments. It delivers 10 W of continuous output power into an 8-ohm load with a supply voltage ranging from 10 V to 26 V. The device features a total harmonic distortion plus noise (THD+N) of 0.09% and operates within a temperature range of -40°C to +85°C. It utilizes a 48-pin HTQFP package for surface-mount installation.

Feature Summary

• Filter-free Class-D architecture eliminates the need for external output filters.
• Integrated protection mechanisms include thermal shutdown and short-circuit protection.
• Supports analog input signals with differential input capability.

Applications

• Portable media players
• Personal computers
• Laptop computers

Procurement Notes

Verify the specific suffix 'PHPR' against the manufacturer's official datasheet to confirm the exact tape-and-reel packaging configuration and moisture sensitivity level. Ensure that the selected component matches the required operating temperature range and package dimensions for your printed circuit board design before finalizing procurement.

Selection Notes

Select this component when a compact stereo solution is required for battery-powered or low-voltage systems. The 10 W output rating suits applications where moderate volume levels are sufficient. Consider the 48-pin HTQFP package constraints during layout planning to ensure adequate thermal dissipation and trace routing capabilities.

Part Context

This part belongs to the TPA3101D2 series, which represents Texas Instruments' portfolio of high-efficiency audio amplifiers.
