Product Description

The TPA3116D2 2.1 Channel Digital Home Theatre Amplifier Board is a high-power audio module designed for high-fidelity sound systems and custom DIY home theatre builds. Utilising two advanced TPA3116D2 digital amplifier chips—one dedicated to the left/right stereo channels and the second bridged for the subwoofer—this module delivers a combined peak power of 200W. Its efficient Class D architecture ensures minimal heat generation while providing clear and punchy audio, making it the perfect choice for upgrading home audio setups, automotive sound systems, or building high-end portable speakers.

Detailed Key Features

  • Powerful 2.1 Audio Architecture: Provides a dedicated 100W subwoofer channel for deep bass and dual 50W satellite channels for precise stereo imaging.

  • Superior Energy Efficiency: Operates at over 90% power efficiency, ensuring the module stays cool even during sustained high-volume playback.

  • Onboard Precision Tuning: Features built-in potentiometers for total volume control, subwoofer frequency adjustment, and individual satellite speaker trimming.

  • Audiophile-Grade Clarity: Boasts a high Signal-to-Noise Ratio (SNR) of 100dB, ensuring a near-silent background and crystal-clear sound reproduction.

  • Robust Safety Protections: Includes integrated safeguards against over-voltage, under-voltage, overheating, and short-circuit conditions for long-term reliability.

Technical Specification in Details

  • Frequency Response Range: Wide range from 14Hz to 100kHz for full spectrum audio coverage.

  • High Switching Frequency: Operates at 1.2MHz switching frequency to minimize audio distortion.

  • Speaker Impedance Compatibility: Supports standard 4Ω to 8Ω speakers for versatile system configuration.

  • Physical Footprint: Compact design measuring 100mm x 70mm x 30mm for easy integration into custom enclosures.

  • Weight Profile: Lightweight at approximately 122 grams, suitable for portable and fixed installations alike.

Prototyping & Engineering Tips (Robogears Exclusive)

  • Power Supply Optimisation: For maximum performance and punchy bass, we strongly recommend a 24V 5A DC power supply; while 12V works, 24V significantly unlocks the board's full potential.

  • Signal Integrity: Use high-quality shielded audio cables for all input connections to prevent electromagnetic interference or humming.

  • Driver Selection: Ensure your subwoofer is rated for at least 100W and your satellite speakers for 50W to prevent damage to the voice coils at peak volume.

  • Heat Management: While highly efficient, ensure adequate airflow around the heatsink if the module is mounted inside a sealed or tight enclosure for prolonged use.

Package Includes

  • 1 x TPA3116D2 2.1 Channel Digital Amplifier Board

  • 1 x Set of Knob Caps and Mounting Spacers
