TPA3116D2 Digital Audio Stereo Amplifier Board, Dual Channel 50W Class D DC K1N2 Chip type: TPA3116D2Power supply: DC 12-24VChannel amount: Dual 50WProduct size: 37.2mm x 25.6mm x 1.5mm(LxWxH)color:blueMaterial: MetalNote:If your power supply and the audio equipment are common ground, when connecting the TV box, there will be a little current noise because this amplifier board does not have noise isolation function for power supply. So, you need a common ground isolation board;Please enhance the heat dissipation such as adding a little heatsink chip on the amplifier board when your power is relatively higher or your amplifier board has been used for a long time.Package Contents:1x Amplifier BoardOnly the above package content, other products are not included.Note: Light and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
