3W*2 Mini Digital Power Audio Amplifier Board DIY Stereo USB DC 5V Power Supply PAM8403 for Arduino

Brand Name:AOKIN Type:Voltage Regulator Condition:New Application:Computer Supply Voltage:2.5V-5V Dissipation Power:2*3W

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.

Description Ultra-mini digital amplifier board, ultra-thin , can be very convenient to place in the gap of small plastic boxes or other devices. It can obtain maximum power output at a lower voltage. Built-in standby electronic switch, high-gain buffer amplifier. New efficient digital amplifier chip Special internal output processing circuit Eliminating the conventional LC network Using EMI
