TPA3116D2 80W+80W Stereo Amplifier Board, Hi-Fi Digital Audio Power Amp Module for Home Theater Car Audio DIY Speaker
Product Description
The module comes with an installed aluminum heat sink placed directly over the TPA3116D2 chip. This helps keep the amplifier cool during long periods of heavy use. The board works with a range of input voltages from DC $12\text{V}$ to $24\text{V}$, which gives you flexibility when powering it from different sources. You’ll find screw terminal blocks on the board for quick and secure connections to both power and speakers. It also has $3.5\text{mm}$ or 3-pin AUX inputs, so connecting your audio source is easy.
Whether you're building custom speaker enclosures, a boombox, or an arcade cabinet with sound, this amplifier module delivers reliable performance at a low cost. It’s an efficient amplification engine that fits well in creative audio projects.
Key Features
High‑Efficiency TPA3116D2 Class‑D Chipset: This chipset can push up to $80\text{W} + 80\text{W}$ of peak power and is then $90\%$ efficient, at converting power and draws very little current when idle.
Dual‑Channel 2.0 Stereo Output: This gives left and right paths, keeps cross‑talk low, delivers deep bass, and keeps high frequencies clear.
Integrated Heavy‑Duty Heat Sink: A pre‑mounted black aluminum heat sink soaks up heat well. Does not need any fans.
Screw Terminal & Header Interfaces: Strong screw‑type terminals make it easy to plug in speaker wire and power without solder. There is also a normal 3‑pin audio input header.
Comprehensive Circuit Protection: The board has built‑in safety that guards against over‑voltage, under‑voltage, excessive heat, DC detection, and short circuits.
