TPA3118 PBTL Mono Digital Audio Amplifier Board – 60W High-Power Class D Module (DC 12V-24V)

Product Description

The TPA3118 PBTL Mono Digital Amplifier Board is a high-performance, compact audio module designed to drive a single high-power speaker with exceptional clarity. By utilizing the PBTL (Parallel Bridge Tied Load) configuration, this board merges the output power to deliver up to 60W from a single channel. Its Class D design ensures extremely high power efficiency, making it an ideal choice for building DIY active subwoofers, professional PA systems, or upgrading single-speaker automotive audio setups. The small footprint and low heat generation make it perfect for integration into tight enclosures where space is at a premium.
