An awesome digital audio amplifier, it's efficient design draws 48 ma @ 24 volts when idling. The TPA3116D2 ic comes from Texas Instruments and features automatic thermal and short circuit protection. The hard work is done because the surface mount amplifier IC is pre-soldered! Jumper points provided on the board for easy selection of stereo or bridged operation. An oversized heatsink means little chance for over heating and will only be warm when cranking up the tunes. Wide supply voltage operation and yes it operates on as little as 5 VOLTS! Modifying this amp with your own unique parts is easy because the board uses standard through hole components. You won't be disappointed by the power, efficiency and frequency response of this amp!
