The TPA3110 XH-A232 2.0 Channel Digital Stereo Amplifier Board is a compact yet high-efficiency audio module designed for high-fidelity sound. At Electrapac, we recommend this board as the perfect "mid-range" amplifier—offering significantly more power than the PAM8403 but remaining more energy-efficient than larger TPA3116 boards.

Product Overview

The XH-A232 utilizes the TPA3110 digital power amplifier chip, delivering 30W + 30W of stereo output. Its standout feature is its ability to produce high volume with very low heat, making it ideal for enclosures with limited ventilation.

Key Features for Electrapac Customers

• Digital Class D Efficiency: Converts over 90% of electrical power into sound, meaning it stays cool even when playing at high volumes for hours.

• Compact Footprint: The small PCB size allows you to integrate professional-grade amplification into tight spaces like bookshelves, small cabinets, or portable suitcases.

• No Heat Sink Required: Due to the high efficiency of the TPA3110 chip, it does not require a bulky aluminum heat sink for standard 12V operation.

• Crystal Clear Stereo: Provides a wide frequency response with very low distortion, delivering the "Hi-Fi" clarity needed for modern music and movies.

• Wide Voltage Range: Runs perfectly on a 12V car battery, a 19V laptop adapter, or a 24V industrial power supply.
