The TPA3118 PBTL Mono Digital Amplifier Board delivers up to 60 W output power using the original Texas Instruments TPA3118 chip. It operates on DC 8–24 V and provides crystal-clear Hi-Fi audio through a Class-D architecture offering low distortion (THD ≤ 0.1%) and high efficiency. Ideal for DIY Bluetooth speakers, robotic voice systems, Arduino sound labs, and Raspberry Pi audio projects.
The board features a professional PCB layout with separated signal and power sections to reduce noise interference. It uses 330 µF 25 V low-ESR capacitors and 10 µH inductors for stable, noise-free output. Integrated reverse-polarity and thermal protection ensure safe operation with 4 Ω and 8 Ω speakers.
Clearly labeled terminals (Power IN, Audio IN, Speaker OUT) make wiring easy, and the MUTE pin allows precise control for projects requiring audio management. Perfect for home theaters, monitor speakers, DIY amplifiers, STEM education labs, and embedded audio applications.TPA3118 PBTL amplifier, digital audio amplifier module, mono 60 W amp board, Class-D audio amp, low-noise amplifier, Arduino audio project, ESP32 sound module, Raspberry Pi amplifier, DIY Bluetooth speaker, Hi-Fi amplifier, Texas Instruments chip, DC 8–24 V input, audio power driver, reverse polarity protection, thermal protection, PWM audio controller, embedded audio system, educational electronics, robot voice amplifier, low distortion amp, STEM learning kit, compact audio amplifier, high efficiency sound board, industrial audio module, mono audio driver, DIY music project, Hi-Fi DC amp, audio signal booster, small power amplifier, portable speaker amp, educational lab board
