TPA3110 2X15W Digital Stereo Audio Power Amplifier Module Board

  • $3.29


This stereo digital audio power amplifier module features a TPA3110 15W per channel high-efficiency Class-D audio power amplifier IC to drive a pair of stereo speakers.

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 stereo 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 sound system with a pair of speakers, and power it from your car's battery, a 12V wall power supply, or 3+ 18650 Li-Ion batteries.
