TPA3110 30W Digital Mono Audio Power Amplifier Module Board

  • $3.89

This mono digital audio power amplifier module features a TPA3110 30W high-efficiency Class-D audio power amplifier IC to drive a single speaker. It can be used alone for public address and other mono applications, or in pairs to build a 30W stereo amplifier. 

The module requires an input DC power supply of 8 to 24 volts at up to 3A current, and an analog audio source. It can drive speakers with impedances as low as 4Ω. With an efficiency of 90%, the TPA3110 eliminates the need for an external heat sink when playing music.

The outputs are fully protected against shorts to GND, VCC, and output-to-output. The short-circuit protection and thermal protection includes an auto-recovery feature.

Build your own audio system powered from your car's battery, a 12V wall power supply, or 3+ 18650 Li-Ion batteries.
