TPA3123D2PWPR

Audio Amplifiers Overview

The TPA3123D2PWPR is a stereo Class-D audio power amplifier manufactured by Texas Instruments. It delivers 25 W of continuous output power into a 4-ohm load with a supply voltage range of 10 V to 30 V. The device features a fixed gain of 36 dB and maintains a total harmonic distortion plus noise (THD+N) of 0.08%. It operates on a single power supply and utilizes an analog input interface. The component is housed in a 24-pin HTSSOP package designed for surface-mount installation, supporting an operating temperature range from -40°C to +85°C.

Audio Amplifiers Feature Summary

• Delivers high-efficiency stereo audio amplification using Class-D topology
• Provides robust protection mechanisms including thermal shutdown and short-circuit protection
• Supports flexible integration through standard analog input interfaces

Audio Amplifiers Applications

• Portable audio devices requiring efficient stereo amplification
• Compact home theater systems
• Active loudspeaker designs

Audio Amplifiers Procurement Notes

Verify the specific suffix 'PWPR' corresponds to the tape-and-reel packaging configuration required for automated assembly processes. Confirm that the HTSSOP-24 footprint matches the target printed circuit board layout. Ensure the selected variant meets the necessary humidity sensitivity level requirements for the intended manufacturing environment.

Audio Amplifiers Selection Notes

Select this component when a dual-channel solution is required within a compact surface-mount form factor. The fixed 36 dB gain simplifies signal chain design by reducing the need for external amplification stages. Consider the 10 V to 30 V supply range compatibility with existing system power rails before finalizing the design.

Audio Amplifiers Part Context

This part belongs to the TPA3123D2 series of audio amplifiers from Texas Instruments. The PWPR suffix indicates the reel-based packaging format, distinguishing it from tube-packaged variants like the TPA3123D2PWP. The series is engineered for applications demanding high power density and efficiency in small footprints.

Audio Amplifiers Replacement Considerations

The TPA3123D2PWP serves as a direct pin-compatible alternative offering identical electrical performance but packaged in a tube instead of a reel.
