TPA3107D2PAPR

Overview

The TPA3107D2PAPR is a 15-W stereo Class-D audio power amplifier in a 64-pin HTQFP package. It operates from a single supply voltage ranging from 10 V to 26 V and drives bridged-tied stereo speakers with impedances as low as 6 Ω. The device features four selectable fixed gain settings of 20, 26, 32, and 36 dB, controlled via GAIN0 and GAIN1 pins. It includes differential inputs, thermal and short-circuit protection with auto-recovery, and a clock output for synchronization.

Feature Summary

• Efficient Class-D operation eliminates the need for external heat sinks during music playback
• Four selectable fixed gain settings (20, 26, 32, 36 dB) via digital control pins
• Integrated thermal and short-circuit protection with an auto-recovery feature
• Clock output capability for synchronizing multiple Class-D devices

Applications

• Televisions
• Powered speaker systems
• Consumer audio equipment

Procurement Notes

Verify the specific ordering suffix 'PAPR' against the manufacturer's Package Option Addendum to confirm the exact tape-and-reel quantity and moisture sensitivity level. Ensure the procurement channel provides documentation confirming RoHS compliance status. Cross-reference the datasheet revision date to validate that all electrical characteristics match the current production standard.

Selection Notes

Select this component when designing systems requiring high-efficiency stereo amplification without external heatsinks. It is suitable for applications needing flexible gain configuration through digital pins. Verify that the PCB layout accommodates the exposed thermal pad on the 64-pin HTQFP package for optimal heat dissipation. Confirm that the system power supply range aligns with the 10 V to 26 V operating limits.

Part Context

This part belongs to Texas Instruments' TPA310x series of efficient Class-D audio power amplifiers. It is designed for driving bridged-tied load (BTL) stereo speakers. The device utilizes advanced modulation schemes to reduce switching losses and improve efficiency compared to traditional Class-D architectures. It is intended for use in portable and stationary consumer electronics where space and thermal management are critical constraints.

Replacement Considerations

Consult the manufacturer's official replacement guide for verified substitutes. Direct pin-to-pin replacements within the same family may require verification of gain settings and package compatibility.
