Wzmacniacz audio TPA3116D2 moduł stereo 2x50W klasa D 12-26V do Arduino

Dual-Channel TPA3116D2 Audio Amplifier

A high-performance Class D audio amplifier module based on the TPA3116D2 chip. The device delivers output power up to 2 x 50 W in a stereo 2.0 configuration. It provides clean, dynamic sound with low distortion (THD+N 0.1%), and works with speakers with an impedance of 4-8 Ω. The module is designed for home systems, portable speakers, and DIY projects that need a reliable audio source.

Key Technical Features

• Output power: 2 x 50 W (4 Ω, Class D)
• Efficiency: over 90%
• Distortion (THD+N at 1 kHz): 0.1%
• Supply voltage: 12-26 V DC (recommended 24 V DC)
• Frequency response: 20 Hz - 20 kHz
• Speaker impedance: 4-8 Ω
• Audio input: line-level (INL/GND/INR) on a 3-pin connector - signal cable approx. 28 cm included
• Speaker outputs: screw terminal block for easy wire mounting
• Protection: over- and undervoltage, short-circuit, thermal, and DC offset detection
• Dimensions: 92 x 68 x 17 mm

Example Applications

Thanks to its high efficiency and compact size, the module is widely used in many electronic devices and projects.

• Building efficient, portable wireless speakers
• Home audio systems and zone sound installations
• Upgrading and repairing older AV equipment
• DIY automation and embedded systems projects (for Arduino, Raspberry Pi, ESP32, ESP8266)
• Sound installations in service points and retail locations

Benefits

The integrated TPA3116D2 chip ensures high energy efficiency while maintaining stable parameters during continuous operation.

• Wide supply voltage range allows flexible power source selection depending on your needs
• Two independent potentiometers enable precise, separate volume control for the left and right channels
• Screw terminals eliminate the need to solder wires, making connection faster and easier
• Built-in protection circuits protect the module from overload, short circuit, and overheating, improving reliability
• High Class D efficiency reduces heat dissipation and enables a compact design
