The mini audio stereo amplifier has two modes: sleeping and working modes. When pin â€œSWâ€ is Low (0V), the amplifierâ€™s bias circuit will be closed, then the module goes into sleep mode, while when pin â€œSWâ€is High (5V), the working mode enables. The audio stereo amplifier is in working mode by default (the pin is unconnected).
This Mini Audio Stereo Amplifier can be used in robot voice system, DIY music box, sound modification. Note:
1. The positive and negative poles are not allowed to be connected reversely.
2. The negative poles for the high and low channels are independent, do not connect them together.
3. The power supply should be no less than 5.5V, too high voltage will damage the IC.
