TPA3107D2PAP

Overview

The TPA3107D2PAP is a 15-W per channel stereo Class-D audio power amplifier in a 64-pin HTQFP package. It operates from a 10-V to 26-V supply and drives loads as low as 6 Ω. The device features four selectable fixed gain settings of 20, 26, 32, and 36 dB controlled by 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 via digital control pins
• Integrated thermal and short-circuit protection with auto-recovery feature
• Clock output capability for synchronizing multiple Class-D devices

Applications

• Televisions
• TV Audio Systems

Procurement Notes

Verify the specific ordering suffix matches the required tape-and-reel or cut-tape packaging configuration. Confirm the HTQFP-64 pinout alignment with your PCB footprint design. Ensure the thermal pad connection strategy meets the datasheet requirements for adequate heat dissipation on the target printed circuit board layout.

Selection Notes

Select this component when driving stereo speakers with impedances down to 6 Ω from a 10-V to 26-V power rail. The fixed gain options simplify input stage design compared to variable gain amplifiers. Consider the 64-pin HTQFP package constraints if space is limited, noting the exposed thermal pad requirement for optimal performance without additional heatsinking.

Part Context

This part belongs to Texas Instruments' TPA31xxD2 series of high-efficiency Class-D audio amplifiers. The series focuses on eliminating external filtering components in many applications while maintaining high output power. The TPA3107D2 specifically targets television and consumer audio equipment requiring robust stereo amplification in a compact surface-mount form factor.

Replacement Considerations

Consult the official TI replacement matrix for verified cross-reference part numbers. Verify pin compatibility and thermal characteristics before substituting.
