TPA3113D2PWPR

Overview

The TPA3113D2PWPR is a 6-W filter-free stereo Class-D audio power amplifier manufactured by Texas Instruments. It operates within a supply voltage range of 5 V to 18 V and supports load impedances of 4 Ω or 8 Ω. The device features an analog input interface with a fixed gain of 20 dB. Key electrical parameters include a total harmonic distortion plus noise (THD+N) of 0.09% at 1 W output, a quiescent current of 7 mA, and a shutdown current of less than 1 µA. It is housed in a 28-pin HTSSOP package and functions across a temperature range of -40°C to +85°C.

Feature Summary

• Integrates SpeakerGuard technology for continuous protection against speaker damage from DC offset, excessive excursion, and over-temperature conditions.
• Eliminates the need for external output filters, reducing component count and board space requirements.
• Includes thermal shutdown and short-circuit protection circuits to ensure robust operation under fault conditions.

Applications

• Portable Bluetooth speakers
• Desktop multimedia speakers
• Active subwoofers

Procurement Notes

Verify the specific suffix 'PWPR' corresponds to the HTSSOP-28 package and tape-and-reel packaging configuration. Confirm RoHS compliance status through the manufacturer's official documentation. Ensure the design accounts for the specified operating temperature range and humidity sensitivity levels during storage and assembly.

Selection Notes

Select this component for applications requiring high efficiency without external filtering components. Compare performance metrics such as THD+N and standby current against alternative models like the TPA3116D2 if higher power output is required. Evaluate the fixed gain configuration against variable gain options if system-level signal conditioning varies.

Part Context

This part belongs to the TPA31xxD2 family of Class-D audio amplifiers from Texas Instruments. The series is characterized by its filter-free architecture and integrated protection features. The PWPR suffix indicates the specific tape-and-reel packaging variant suitable for automated surface-mount assembly processes.

Replacement Considerations

The TPA3113D2PWP is the tube-packaged equivalent of this component. Verify pin compatibility and thermal characteristics when substituting between reel and tube variants.
