Texas Instruments TPA3118 Amplifier

This compact Class D amplifier uses a Texas Instruments TPA3118 chip to deliver clean, efficient stereo audio. It is suited for DIY enthusiasts, arcade cabinet builders or anyone adding sound to a small home or automotive setup. The lightweight aluminium enclosure includes mounting tabs for secure installation. A 12 VDC, 3 A power supply is included in the package.

Sustained Operation

The Class D topology keeps power consumption low and heat generation minimal during extended listening sessions. The aluminium chassis acts as a heatsink, allowing the amplifier to maintain stable performance without thermal throttling. No fan is present, so operation remains completely silent. The included 12 V, 3 A supply provides consistent current for continuous playback at typical volumes.

Connectivity Limits

Input options are a 3.5 mm stereo jack and gold-plated RCA sockets, restricting sources to analogue line-level devices. There is no Bluetooth, Wi-Fi, digital optical or USB audio interface built in. Speaker terminals accept bare wire only; banana plugs or spade connectors cannot be used. The fixed 12 V input voltage prevents direct connection to higher-voltage DC systems without an external regulator.

Questions about this item

Does the TPA3118 chip get hot during long listening sessions?

The Class D TPA3118 runs efficiently and the aluminium enclosure acts as a heatsink, so it stays cool even after hours of use.

What cables do I need to connect my phone or turntable to the 3.5 mm and RCA inputs?

Use a 3.5 mm stereo cable for phones or portable players, and standard RCA interconnects for a turntable or CD player; both plug straight in.

Will this amplifier drive my older 8-ohm bookshelf speakers without distortion?

The TPA3118 delivers clean power into typical home speakers, and the gold-plated RCA inputs ensure a solid connection with vintage gear.
