Clyxgs TPA3116D2 Dual-Channel Class D Amplifier Board

This slim amplifier module pairs the proven TPA3116 core with onboard pre-amplification and protection circuits to produce clean, powerful output while staying thermally efficient. Its small 92×68×16mm footprint, European-style wiring terminals, and convection heatsink make it suitable for integrating into vehicle audio upgrades, small powered speakers, or custom media-player enclosures.

How much power can I expect from this amplifier?

The board is rated to deliver up to 120W per channel when powered near the top of its input range, with typical operation at 50W per channel from a 12V supply. Power output depends on supply voltage, speaker impedance, and thermal conditions.

• Rated outputs: 50W × 2 at DC12V; up to 120W × 2 at DC24V.
• Maximum output limited by supply voltage (DC12–26V supported).
• Optimal matching requires suitable speakers and adequate ventilation.

What protections and features keep the board reliable?

The module uses an efficient Class D power amplifier chip with integrated protection and surface-mounted components for stable operation. Built-in circuits guard against overvoltage, undervoltage, overheating, DC faults and short circuits to protect both the amplifier and connected speakers.

• Integrated protections: over/under voltage, thermal shutdown, DC and short-circuit detection.
• High-efficiency design (>90% power efficiency) reduces idle loss and heat generation.
• Large heatsink and convection cooling support sustained operation without forced fans.

How do I connect and use this amplifier in my project?

Connections are made via European-style 3P screw terminals for power and speaker outputs, plus standard input pins for left/right signals. The pre-board IC increases input sensitivity, so you can drive the board from common line-level sources like head units, PCs, or DACs.

• Power: DC12–26V input; observe correct polarity and adequate current rating.
• Speaker outs: dual-channel stereo via screw terminals; match load impedance for best results.
• Signal input: use line-level sources; adjust source volume before the board for clean gain staging.

What size and installation considerations should I know?

Measuring 92×68×16mm, the amplifier fits small enclosures and can be mounted to a chassis with attention to airflow. Keep clearance around the heatsink and avoid tightly sealed boxes; consider adding ventilation or a chassis-mounted heat path for sustained high-power use.

• Compact dimensions enable placement inside cabinets or vehicle spaces.
• Convection heatsink requires free air for thermal performance.
• Use appropriately rated power supply and wiring to prevent voltage drop under load.

Who is this for: The Clyxgs TPA3116D2 amp board is aimed at hobbyists, DIY audio builders, car audio enthusiasts and small-system installers needing a compact, high-efficiency stereo amplifier. It suits projects that require significant output without large power loss, such as powered bookshelf speakers, portable PA modules, or vehicle upgrades, provided installers follow proper wiring and cooling practices.
