PAM8302 2.5W Single Channel Class D Amplifier

PAM8302 2.5W Single Channel Class D Amplifier development board has a filterless design and output with ferrite bead + capacitors. This design is very convenient for people to use, can improve efficiency, and can feel the product’s benefits when they use it.

24DB FIXED GAIN: The product has a 24dB fixed gain and onboard trimmer potentiometer for input volume adjustment. This design facilitates the use and operation of the product by customers. Customers can adjust the volume according to the situation.

THERMAL AND SHORT-CIRCUIT/OVER-CURRENT PROTECTION: Single channel power amplifier has thermal and short-circuit/over-current protection. This design can improve the safety of the product during operation, will not cause problems such as short circuits, and will avoid some troubles for the user

PAM8302 output is “Bridge Tied”, meaning that the output pins connect directly to the speaker connections without connection to the ground.

The left and right channel “negative” connections should not be connected, and the amplifier’s output should not be connected to another amplifier; it should drive the speakers directly.

Specifications:
