Product Description

The TPA3110 Dual Channel Stereo Amplifier Board is an exceptionally efficient Class D power module designed to deliver crystal-clear audio with minimal heat dissipation. Capable of outputting 15W per channel, this board utilises the advanced TPA3110 chip, which eliminates the need for bulky external heatsinks during normal operation. It is an ideal choice for DIY Bluetooth speakers, television audio upgrades, and desktop monitor sound systems. At Robogears, we recommend this module for its wide operating voltage range and its ability to drive 8-ohm speakers with high-fidelity precision, making it a versatile component for professional-grade audio projects.

Detailed Key Features

Superior Power Efficiency: The Class D architecture ensures over 90% efficiency, allowing the board to remain cool even during sustained high-volume playback without a dedicated heatsink.
Flexible Voltage Input: Operates reliably across a broad range of 8V to 24V DC, making it compatible with various power sources, including 12V batteries and 24V industrial adapters.
High-Fidelity Audio Signal: Engineered with high-quality surface-mount components to provide an excellent signal-to-noise ratio and superior stereo separation.
Ultra-Compact Filterless Design: Reduces the overall footprint while maintaining audio integrity, perfect for space-constrained enclosures in portable devices.
Integrated Hardware Protection: Features built-in circuitry to safeguard against over-voltage, under-voltage, and short-circuit conditions, ensuring long-term module durability.

All Technical Details

Frequency Response Range: 20Hz – 20kHz for full-spectrum audio fidelity.
Peak Output Power: Delivers 15W + 15W at optimized loads (12V 4Ω or 24V 8Ω).
Quiescent Current Consumption: Ultra-low idle draw of 20mA.
Signal Input Interface: Standard 3-pin header (Left-Ground-Right) for easy wiring.
Module Dimensions: Compact footprint of 33mm x 25mm x 3mm for versatile mounting.

Prototyping & Engineering Tips (Robogears Exclusive)

Power Supply Optimization: To achieve the best audio performance and avoid interference, we suggest using a regulated 12V 3A or 19V 3A power supply.
Signal Integrity: Ensure that the power supply leads are as short as possible and use high-quality shielded audio cables for the input signal to minimize hum.
Speaker Matching: Avoid using speakers with an impedance lower than 4 ohms, as this may trigger the thermal protection or permanently damage the IC at higher operating voltages.
Vibration Management: When mounting inside a speaker cabinet, use small rubber spacers to prevent mechanical vibrations from affecting the surface-mount components on the board.

Package Includes

1 x TPA3110 Audio Amplifier Module (15W + 15W)
