Product description: MAX98306 - Class D audio amplifier 3.7 W stereo
The MAX98306 Class D audio amplifier module features low power loss, meaning low heat generation, and long battery life. It can connect a 3Ω speaker with up to 3.7W of power.
The system's advantage is its differential inputs, which protect the input signal coming from the main circuit, such as the Arduino Mp3 Shield available in our store. If you don't have a device with a differential output, connect pins R and L to ground.
The module's output is "bridge-tied." This means the output pins are connected directly to the speaker pins, with no connection to ground. The output is a 360 kHz PWM signal, which is averaged by the speaker coil—high frequencies are inaudible. Another amplifier cannot be connected to the module; it should be connected directly to the speakers.
The set includes connectors for self-soldering .
