TPA3112D1PWPR

Overview

The TPA3112D1PWPR is a single-channel mono Class-D audio amplifier manufactured by Texas Instruments. It delivers 25 W of output power into an 8-ohm load with a total harmonic distortion plus noise of 0.05%. The device operates on a single supply voltage ranging from 8 V to 26 V and draws a typical quiescent current of 40 mA. It is housed in a 28-pin HTSSOP package designed for surface mount installation. The component functions within a temperature range of -40°C to +85°C.

Feature Summary

• Filter-free design eliminates the need for external output filters, reducing bill of materials and board space.
• Integrated SpeakerGuard technology provides comprehensive protection against short circuits, thermal overload, and DC faults.
• Supports differential input signals to improve noise immunity and signal integrity in noisy environments.

Applications

• Audio equipment
• Televisions

Procurement Notes

Verify the specific suffix 'PWPR' corresponds to the HTSSOP-28 package and tape-and-reel quantity requirements. Confirm that the application environment remains within the specified -40°C to +85°C operating temperature range. Ensure the power supply voltage does not exceed the maximum rating of 26 V to prevent device damage. Check for moisture sensitivity level compliance during storage and handling procedures.

Selection Notes

Select this component when a high-efficiency mono amplifier is required for driving 8-ohm speakers without external filtering. It is suitable for designs needing robust speaker protection features integrated directly into the amplifier IC. Consider the 28-pin HTSSOP footprint for PCB layout constraints. Evaluate the 25 W power capability against the specific acoustic requirements of the target application.

Part Context

This part belongs to the TPA3112D1 series of filter-free Class-D audio amplifiers. It shares the core architecture with other variants like the TPA3112D1PWP but differs in packaging and reel specifications. The series is characterized by its high efficiency and integrated protection mechanisms, making it a standard choice for consumer audio electronics requiring reliable mono amplification.

Replacement Considerations

The TPA3112D1PWP serves as a tube-packaged alternative within the same functional family. For automotive applications, the TPA3112D1QPWPRQ1 offers AEC-Q100 qualification and extended temperature ranges. Verify pin compatibility and thermal performance before substituting any variant.
