TPA3118 Power Amplifier Board Module – PBTL 60W Mono Digital Class-D

The TPA3118 power amplifier board is a compact, high-efficiency Class-D amplifier module designed for DIY audio projects. In PBTL mono mode, it delivers strong output for driving a single speaker channel with clean sound and low heat, ideal for custom speaker builds, small PA experiments, and home audio upgrades.

Uses

• DIY mono speaker builds and compact amplifier projects

• Sub/low-end single-channel builds (with proper filtering and speaker choice)

• TV/monitor audio upgrades and custom enclosures

• Student/STEM audio experiments and prototyping

Features

• PBTL mono Class-D amplifier design

• Output power: up to 60W (depends on supply voltage and speaker impedance)

• Input voltage: DC 10–24V

• Efficient design for less heat and smaller power supply size

• Screw terminals for easier wiring (board layout dependent)

How to use

• Connect DC power (10 – 24V) to V+ and GND

• Connect audio input to IN terminals

• Connect speaker output to OUT terminals (mono)

• Use a stable power supply for best performance and less noise

Notes (important)

• Real output depends on your power supply, speaker impedance and wiring quality

• For best results, use a good DC adapter and decent speaker cable

• Keep input and power wires tidy to reduce hum/noise
