Product Description

The TPA3116D2 Dual-Channel Digital Amplifier Board is a high-performance audio powerhouse designed to deliver professional-grade sound for home theatres and DIY stereo builds. Utilising two advanced TPA3116D2 chips in a bridged configuration, this module provides a massive 200W total output (100W per channel). Its Class D architecture ensures exceptional power efficiency and minimal heat generation, allowing for sustained high-volume playback. Whether you are building custom tower speakers or high-fidelity desktop audio systems, this board offers the clarity, stability, and raw power required for a premium listening experience.

Detailed Key Features

High-Power Stereo Output: Delivers a crisp 100W per channel, capable of driving large bookshelf and floor-standing speakers with ease.
Dual-Chip Architecture: Uses two high-performance TPA3116D2 ICs to maximise power delivery and thermal stability.
Extreme Energy Efficiency: Operates with over 90% efficiency, keeping the board cool and reducing power consumption from your DC source.
Audiophile-Grade SNR: Features a 100dB Signal-to-Noise Ratio, providing a crystal-clear audio signal with a virtually silent background.
Comprehensive Safety Protections: Integrated safeguards against over-voltage, under-voltage, overheating, DC detection, and short-circuit conditions ensure long-term durability

Brief Technical Details

Frequency Response: Supports a wide range from 20Hz to 20kHz for full-spectrum audio fidelity.
Speaker Impedance: Compatible with standard 4Ω to 8Ω speakers for versatile system pairing.
Input Interface: Features a 3-pin audio input header and standard screw terminals for secure power and speaker connections.
Thermal Management: Equipped with a large-area aluminium heatsink to maintain optimal operating temperatures under heavy load.
Dimensions: Compact and robust PCB layout designed for easy mounting within custom enclosures.

Prototyping & Engineering Tips (Robogears Exclusive)

Power Supply Selection: To achieve the full 100W + 100W output, a high-quality 24V 8A to 10A DC power supply is strongly recommended. Powering the board at 12V will result in significantly lower volume and reduced bass impact.
Heat Dissipation: If installing this board in a tight or unventilated enclosure, consider adding a small cooling fan to assist the onboard heatsink during extended high-power use.
Speaker Pairing: Ensure your speakers are rated for at least 100W RMS. Using under-powered speakers at high volumes may cause voice coil damage due to the board's high output capability.
Input Isolation: For the cleanest sound at your Pimpri workshop, use shielded audio cables to minimize electromagnetic interference from nearby power sources or motors.
