WONDOM 1X 60W Class D Audio Amplifier Board Mono -TPA3118 AA-AB31211

Description

1 X 60Watt Class-D Audio Amplifier Board - TPA3118
（
AA-AB31211

manual：
AA-AB31211
DESCRIPTION
It is a mono Class D audio amplifier board capable of delivering 60W @ 4 Ohm. It employs TI' TPA3118 Amplifier IC to achieve extreme efficiency up to 95%. The module dissipates only 0.7W with no signal when in ON mode (around 0.1W 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.
