  • I built a mechanized owl/scarecrow to keep birds off the patio, and after keeping it energized all day, the board died

More about Audio IC Development Tools Adafruit Mono 2.5W Class D Audio Amplifier - PAM8302 (1 piece)

  • This super small mono amplifier is surprisingly powerful - able to deliver up to 2.5 Watts into 4-8 ohm impedance speakers
  • Inside the miniature chip is a class D controller, able to run from 2.0V-5.5VDC
  • Since the amp is a class D, its very efficient (over 90% efficient when driving an 8Ω speaker at over half a Watt) - making it perfect for portable and battery-powered projects
  • It has built in thermal and over-current protection but we could barely tell it got hot
  • There's even a volume trim pot so you can adjust the volume on the board down from the default 24dB gain
  • This board is a welcome upgrade to basic "LM386" amps! The A+ and A- inputs of the amplifier go through 1.0uF capacitors, so they are fully 'differential' - if you don't have differential outputs, simply tie the Audio- pin  to ground
  • The output is "Bridge Tied" - that means the output pins connect directly to the speaker pins, no connection to ground
  • The output is a high frequency 250KHz square wave PWM that is then 'averaged out' by the speaker coil - the high frequencies are not heard
  • All the above means that you can't connect the output into another amplifier, it should drive the speakers directly
  • Comes with a fully assembled and tested breakout board
  • We also include header to plug it into a breadboard and a 3.5mm screw-terminal blocks so you can easily attach/detach your speaker
  • You will be ready to rock in 15 minutes! Speaker is not included, use any 4 ohm or greater impedance speaker.Output Power: 2.5W at 4Ω, 10% THD, 1.5W at 8Ω, 10% THD, with 5.5V Supply50dB PSRR at 1KHzFilterless design, with ferrite bead + capacitors on output.Fixed 24dB gain, onboard trim potentiometer for adjusting input volume.Thermal and short-circuit/over-current protectionLow current draw: 4mA quiescent and 1uA in shutdown mode
