TPA3117D2RHBR

Overview

The TPA3117D2RHBR is a stereo Class-D audio power amplifier manufactured by Texas Instruments. It delivers up to 15 W of continuous output power per channel into an 8-ohm load with a 24-V supply. The device operates from a single power supply ranging from 8 V to 26 V and features analog input. It utilizes a 32-pin VQFN package (RHB) designed for space-constrained applications. Key electrical specifications include a minimum operating temperature of -40°C and a maximum of +85°C, along with a typical quiescent current of 25 mA.

Feature Summary

• Filter-free operation eliminates the need for external output filters, reducing component count and board space.
• Integrated SpeakerGuard technology provides protection against speaker faults and thermal overload.
• High efficiency Class-D architecture minimizes heat generation, often removing the requirement for external heat sinks.

Applications

• Portable multimedia speakers
• Desktop audio systems
• Home theater receivers

Procurement Notes

Verify the specific suffix 'RHB' corresponds to the 32-pin VQFN package and tape-and-reel delivery format. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Ensure the ordering part number matches the exact datasheet revision to avoid pinout or functional discrepancies during integration.

Selection Notes

Select this component when high-efficiency stereo amplification is required without external filtering components. It is suitable for designs powered by 8 V to 26 V rails where thermal management must be minimized. Consider the 32-pin VQFN footprint constraints and ensure adequate PCB copper area for thermal dissipation given the 15 W per channel capability.

Part Context

This device belongs to the TPA311x series of filter-free Class-D amplifiers from Texas Instruments. It shares architectural similarities with other members like the TPA3118 but offers lower power output optimized for compact stereo applications. The family emphasizes ease of design-in through reduced external component counts and integrated protection features.

Replacement Considerations

Direct substitutes within the same package and functionality may include other TPA311x variants such as the TPA3116D2 or TPA3118D2, provided power ratings and pin compatibility are verified against the specific application requirements.
