TPA3107D2PAPTG4

Overview

The TPA3107D2PAPTG4 is a 15-W per channel stereo Class-D audio power amplifier manufactured by Texas Instruments. It operates from a single supply voltage ranging from 10 V to 26 V and drives 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 utilizes an efficient modulation scheme that eliminates the need for external output LC filters in most applications. The amplifier includes thermal and short-circuit protection with auto-recovery functionality.

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) configured via digital input pins
• Integrated thermal and short-circuit protection with automatic recovery feature
• Clock output capability allows synchronization with multiple Class-D devices

Applications

• Television audio systems
• Powered speaker enclosures
• Home theater amplifiers

Procurement Notes

Verify the specific PAP suffix indicates the HTQFP-64 package variant. Confirm RoHS compliance status matches current manufacturing standards. Ensure the ordering code aligns with the required tape and reel packaging format for automated assembly processes.

Selection Notes

Select this component when designing stereo audio systems requiring high efficiency without external output filtering. Consider the 10 V to 26 V operating range and differential input requirements. Evaluate the 64-pin HTQFP package constraints for PCB layout and thermal dissipation needs.

Part Context

This part belongs to the TPA310x series of Class-D audio amplifiers from Texas Instruments. It is designed for driving stereo speakers efficiently. The device integrates advanced modulation technology to reduce switching losses and improve overall system performance in compact audio designs.

Replacement Considerations

TPA3100D2PHPG4: Higher power output (21.8 W), different package (HTQFP-48). TPA3120D2PWP: Different package (HTSSOP-24), higher power (25 W). Verify pin compatibility and thermal requirements before substitution.
