The module features a class D audio amplifier controller IC, able to operate from 2.0V-5.5V DC input. Since the amp is class D operation, its very efficient (over 90% efficient when driving an 8Ω speaker at over 1/2 Watt), making it perfect for portable and battery-powered DIY projects . The module has 24dB gain, with a trim pot to adjust the volume on the board down from 24dB. The A+ and A- audio inputs of the amplifier go through 1.0uF capacitors, so they are fully 'differential'. If your audio source does not have differential outputs, simply tie the "Audio -" pin to ground. The output is "Bridge Tied", meaning that the output pins connect directly to the speaker connections with no connection to ground. The left and right channel "negative" connections should not be connected together, and the amplifier's output should not be connected to another amplifier, it should drive the speakers directly. Specifications: Size: 24mm x 16mm (0.95 x 0.63 inches) PSRR (power supply ripple rejection): 50dB at 1KHz Filterless design Fixed 24dB gain, onboard trim potentiometer for adjusting input volume Thermal and short-circuit/over-current protection Low current draw: 4mA quiescent and 1uA in shutdown mode Shutdown pin (SD) can be connected to ground to mute the amplifier's output Output Power: 2.5W at 4Ω, 10% THD, 1.5W at 8Ω, 10% THD, with 5.5V supply Input Voltage Vin: 2.0V - 5.5V DC, 5.0V recommended Speaker Load: 4-8 Ohms Package Includes: 1 x PAM8302A 2.5W Class D Mono Audio Power Amplifier Module Header pins Link to online specifications and usage instructions Get it faster!
