Description
Special Note:
1: The positive and negative poles of the power supply cannot be reversed. The power supply voltage must not exceed 5.5V. Otherwise, the IC may be damaged.
2: There is a high gain buffer in the product, and any component parameters on the board cannot be changed. Inconsistent parameters will cause IC damage.
3: Input lines Please use shielded wires as much as possible to provide anti-interference and eliminate clutter current.
4: The output is a CMOS BTL driving mode. The negative electrodes of the left and right speakers cannot be connected together. That is, the 4 lines connecting the speakers are completely independent and are not allowed to share.
