Overview

The TPA3110D2EVM is a complete evaluation module for the TPA3110D2, a high-efficiency Class D stereo audio power amplifier. It is designed to drive speakers as low as 4 Ohms and supports a wide supply voltage range from 8V to 26V. The board demonstrates the SpeakerGuard protection circuitry, which includes an adjustable power limiter and DC detection to protect connected transducers.

Why Choose This Part

This evaluation board allows for immediate testing of 15W per channel stereo performance into 8 Ohm loads without custom PCB fabrication. It features high efficiency which eliminates the need for external heat sinks in most configurations, while the SpeakerGuard technology ensures reliable operation by preventing speaker damage during clipping or fault conditions.

Applications

Consumer Audio Systems
Prototyping for bookshelf speakers, soundbars, and powered docking stations.
Public Address Systems
Implementing energy-efficient audio amplification for small-scale paging or background music systems.
Self-Service Kiosks
Integrating robust audio output into interactive terminals and automated teller machines.
