TPA3118D2QDAPRQ1

Overview

The TPA3118D2QDAPRQ1 is a dual-channel Class-D audio power amplifier from Texas Instruments, designed for automotive applications. It delivers up to 30W of output power per channel into an 8-ohm load with a supply voltage range of 4.5V to 26V. The device features analog input and hardware control interfaces. It operates within a temperature range of -40°C to 125°C and is housed in a 32-pin HTSSOP package.

Feature Summary

• AEC-Q100 qualified for automotive reliability standards
• Filter-free design simplifies board layout
• Integrated AM rejection capabilities
• Built-in thermal and short-circuit protection

Applications

• Automotive infotainment systems
• Car door speaker amplification
• Center channel audio processing
• Subwoofer driver stages

Procurement Notes

Verify the specific suffix QDAPRQ1 against the manufacturer's current datasheet to confirm pinout and electrical characteristics match your design requirements. Ensure the component meets AEC-Q100 grade specifications for your target automotive environment. Cross-reference the package dimensions with your PCB footprint library before finalizing procurement.

Selection Notes

Select this component when designing stereo audio stages requiring high efficiency and minimal external filtering. It is suitable for applications needing robust performance across wide supply voltages typical in vehicle electrical systems. Consider the thermal management requirements associated with 30W output in enclosed automotive enclosures.

Part Context

This part belongs to the TPA311xD2-Q1 family of filter-free Class-D stereo amplifiers. It shares architectural similarities with other members like the TPA3116D2-Q1 but offers lower power output optimized for specific channel configurations. The family is characterized by its integrated AM rejection and compact HTSSOP packaging.

Replacement Considerations

The TPA3118D2DAPRQ1 is a direct non-automotive grade equivalent. For higher power needs, consider the TPA3116D2QDAPRQ1. Verify that any substitute maintains the same 32-pin HTSSOP footprint and AEC-Q100 qualification if automotive compliance is mandatory.
