Description

This mono Class D audio amplifier board is capable of delivering 40W @ 4 Ohm. It employs TI' TPA3118 Amplifier IC to achieve high efficiency and good performance. The module dissipates only 0.9W with no signal when in ON mode (around 0.01W when in stand-by mode). Excellent heat dissipation eliminates the need for an extra heatsink and ensures its reliability. Over current protection, over temperature protection and reverse polarity protection are included to extend the longevity of the amplifier board.
