Description 3W mini audio stereo amplifier
This is a Mini Audio Stereo Amplifier from DFRobot. It has left and right channels which can realize stereo surround sound. The module has a mini body and 2,54mm pin pitch, convenient to be embedded in any device. Using a stereo speaker, you can control the audio amplifier without programming.
The mini audio stereo amplifier has two modes: sleep and work modes. When pin "SHDN" is low (0V), the amplifier bias circuit is closed. The module will then go into sleep mode. When pin "SHDN" is high (5V), it will enter working mode. The audio stereo amplifier is in working mode by default (the pin is not connected).
This mini audio stereo amplifier can be used in robotic tuning systems, DIY music boxes, sound modification.
Note:
1. The positive and negative poles must not be connected in reverse.
2. The negative poles for the high and low channels are independent, do not connect them together.
3. The power supply should not be less than 5,5V, too high voltage will damage the IC.
