TPA3107D2PAPT

Overview

The TPA3107D2PAPT is a 15-W per channel 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. The device delivers 15 W into an 8-Ω load at 16 V with 10% THD+N. Key electrical parameters include a quiescent current of 22 mA, a gain range of 20 dB to 36 dB selectable via pins, and a thermal trip point of 150 °C. It supports loads as low as 6 Ω.

Feature Summary

• High-efficiency Class-D operation eliminates the need for external heat sinks during typical music playback.
• Four selectable fixed gain settings (20, 26, 32, 36 dB) controlled by digital input pins.
• Integrated thermal protection and short-circuit protection with auto-recovery features.
• Clock output capability allows synchronization with multiple Class-D devices.

Applications

• Televisions
• Powered speakers
• Consumer audio equipment

Procurement Notes

Verify the specific suffix 'PAPT' corresponds to the HTQFP-64 tray packaging configuration. Confirm RoHS compliance status and lead-free soldering requirements against the latest manufacturer documentation. Ensure ESD handling protocols are followed due to MOS gate sensitivity.

Selection Notes

Select this component for applications requiring high power density without active cooling. The differential or single-ended analog inputs provide flexibility. Consider the variable input impedance based on gain selection when designing input coupling networks. Verify PCB thermal pad connectivity for optimal heat dissipation.

Part Context

This part belongs to the TPA310x series of efficient Class-D amplifiers designed for driving bridged-tied stereo speakers. It utilizes adaptive dynamic range control to improve clipping performance. The device integrates internal biasing and regulation, reducing external component count compared to discrete solutions.

Replacement Considerations

Check datasheet compatibility for pin-to-pin replacements within the same family. Verify that alternative models support the required 10 V to 26 V supply range and 15 W output power specifications.
