TPA3110D2PWPR

Overview

The TPA3110D2PWPR is a 15-watt per channel stereo Class-D audio power amplifier manufactured by Texas Instruments. It operates from a single supply voltage ranging from 8 V to 26 V and delivers 15 W into an 8-ohm load at 10% THD+N. The device features a 2-channel stereo output with analog differential inputs and a fixed gain of 36 dB. It utilizes a 28-pin HTSSOP package and supports operation temperatures between -40°C and +85°C. Total Harmonic Distortion plus Noise is specified at 0.1%.

Feature Summary

• Filter-free operation enabled by advanced EMI suppression technology, eliminating the need for external output filters.
• Integrated SpeakerGuard protection circuitry providing adjustable power limiting and DC detection to prevent speaker damage.
• High efficiency performance reaching 90%, which reduces thermal requirements and allows operation without external heat sinks.
• Robust protection mechanisms including short-circuit protection against ground, supply, and output-to-output shorts with automatic recovery.

Applications

• Television sets
• Consumer audio equipment

Procurement Notes

Verify the specific suffix 'PWPR' indicates tape-and-reel packaging distinct from the tube-packaged 'PWP' variant. Confirm AEC-Q100 qualification status if automotive application is required, as standard versions may differ from the Q1 grade. Ensure input signal compatibility with the specified 36 dB fixed gain configuration.

Selection Notes

Select this component for applications requiring high-efficiency stereo amplification without external filtering components. It is suitable for designs needing robust speaker protection and wide supply voltage flexibility. Consider the thermal management benefits of its high efficiency when designing compact enclosures.

Part Context

This part belongs to the TPA3110D2 series of filter-free stereo Class-D audio amplifiers. It shares the same core architecture and protection features as other variants in the family, differing primarily in packaging and reel specifications. The series is designed for cost-effective, high-performance audio solutions in consumer electronics.

Replacement Considerations

TPA3110D2PWP is a pin-compatible alternative available in tube packaging rather than tape-and-reel format.
