Giới thiệu 1 bảng mạch khuếch đại âm thanh kỹ thuật số mini pam8403 công suất cao 3W và 1 kênh đôi Pam8610 2 X15W tại Lotte Market
2pcs Power Amplifier Board : 1pcs el number PAM8610 & 1pcs el numbe PAM8403,colour: black & Red ,Material: plastic & Metal ,size: Amplifier board size: 30mm * 25mm * 2.5mm & 24 x 15.5 x mm
Matters needing attention:Power positive and negative can not be reversed, the power supply voltage can not exceed 5.5V, these two violations will cause IC damage.
On-chip high gain buffer, can not change any component parameters on board, the parameters do not meet will lead to IC damage.
Input line, please use the shielded line as far as possible, can play an anti-interference role, eliminate the noise of the current of the wave.
The output is CMOS tube BTL drive e, the negative electrode of the left and right speakers can not be connected together, that is, the 4 lines of the speaker are completely independent, and no joint connection is allowed!
