TPA3107D2PAPRG4

Overview

The TPA3107D2PAPRG4 is a stereo Class-D audio power amplifier manufactured by Texas Instruments. It delivers 15 W per channel into an 8-ohm load from a 16-V supply. The device operates on a supply voltage ranging from 10 V to 26 V and features four selectable fixed gain settings: 20, 26, 32, and 36 dB. It utilizes differential inputs and incorporates thermal and short-circuit protection with auto-recovery capabilities. The component is housed in a surface-mount 64-pin HTQFP package measuring 10 mm by 10 mm.

Feature Summary

• Efficient Class-D operation eliminates the need for external heat sinks during music playback
• Four selectable fixed gain settings controlled via dedicated input pins
• Integrated thermal and short-circuit protection with auto-recovery functionality
• Clock output pin enables synchronization with multiple Class-D devices

Applications

• Televisions
• TV Audio Systems
• Processor-based Audio Interfaces

Procurement Notes

Verify the specific ordering suffix RG4 against current manufacturer documentation to confirm lead-free status and RoHS compliance. Confirm the HTQFP package designation matches the required PCB footprint. Ensure the revision level aligns with the latest datasheet specifications before finalizing procurement orders.

Selection Notes

Select this component for designs requiring high-efficiency stereo amplification without external heatsinking. Verify that the system supply voltage remains within the 10 V to 26 V operational range. Ensure the application supports the 64-pin HTQFP package dimensions and thermal pad requirements for proper heat dissipation.

Part Context

This part belongs to the TPA3107D2 series of stereo Class-D audio power amplifiers. It is designed for driving bridged-tied load (BTL) stereo speakers with impedances as low as 6 ohms. The device integrates advanced modulation schemes to reduce switching losses and improve efficiency compared to traditional Class-D architectures.
