The TPA3110 XH-A232 is a compact, high-efficiency Class-D stereo audio amplifier board designed for DIY audio projects, portable speakers, home audio systems, and professional sound applications. Built around the Texas Instruments TPA3110 chip, this board delivers 30W per channel (stereo) with exceptional clarity and minimal distortion, all in a footprint measuring just 53 × 45 mm.
This C6-001 (New Version) represents the updated board revision, featuring improved PCB layout and optimized component placement for enhanced stability and performance compared to the original version. The new version maintains the same proven TPA3110 amplifier core while benefiting from manufacturing refinements that improve reliability and audio quality.
At the heart of the board is the TPA3110D2 Class-D amplifier IC, which operates with up to 90% efficiency — eliminating the need for bulky external heat sinks and making the board ideal for compact, portable designs. The board supports a wide DC input voltage range of 8V to 26V with a current requirement of 3A or higher, providing flexible power options for various setups. The signal-to-noise ratio of 100dB ensures clean, detailed audio reproduction with minimal background noise.
The amplifier board features 2.0 channel stereo output, capable of driving speakers with 4–8Ω impedance at up to 30W+30W. The SpeakerGuard™ protection circuitry includes adjustable power limiting and DC detection, protecting both the amplifier and connected speakers from damage. Additional built-in protections include short-circuit protection, thermal protection, and reverse polarity protection.
The board uses surface-mount components and a compact layout that fits easily into small enclosures, custom speaker builds, and portable audio projects. The new version features improved thermal management and optimized trace routing for better performance under sustained high-power operation.
Whether you are building a portable Bluetooth speaker, upgrading a computer audio setup, or creating a custom sound system, the TPA3110 XH-A232 provides a reliable, efficient, and cost-effective amplification solution. It is suitable for individual makers, students, and businesses purchasing in bulk for product development or educational programs.
