Top 10 Best adafruit mono 2.5w class d audio amplifier – in 2022 Comparison Table

Bestseller No. 1
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.
  • 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.

Our Best Choice: Audio IC Development Tools Adafruit Mono 2.5W Class D Audio Amplifier – PAM8302 (1 piece)


Our rating:4.8 out of 5 stars (4.8 / 5)





This tremendous smaller mono amplifier is remarkably potent – equipped to supply up to 2.5 Watts into 4-8 ohm impedance speakers. Inside of the miniature chip is a class D controller, capable to operate from 2.0V-5.5VDC. Given that the amp is a class D, its extremely economical (above 90% productive when driving an 8Ω speaker at around fifty percent a Watt) – creating it ideal for portable and battery-driven initiatives. It has developed in thermal and over-latest security but we could hardly convey to it got warm. There’s even a quantity trim pot so you can alter the quantity on the board down from the default 24dB acquire. This board is a welcome update to basic “LM386” amps! The A+ and A- inputs of the amplifier go via 1.0uF capacitors, so they are entirely ‘differential’ – if you do not have differential outputs, simply tie the Audio- pin to ground. The output is “Bridge Tied” – that signifies the output pins connect straight to the speaker pins, no relationship to ground. The output is a high frequency 250KHz square wave PWM that is then ‘averaged out’ by the speaker coil – the superior frequencies are not listened to. All the previously mentioned indicates that you can’t join the output into another amplifier, it should generate the speakers specifically. Arrives with a fully assembled and tested breakout board. We also incorporate header to plug it into a breadboard and a 3.5mm screw-terminal blocks so you can very easily connect/detach your speaker. You will be all set to rock in 15 minutes! Speaker is not provided, use any 4 ohm or higher impedance speaker. Output Energy: 2.5W at 4Ω, 10% THD, 1.5W at 8Ω, 10% THD, with 5.5V Provide 50dB PSRR at 1KHz Filterless structure, with ferrite bead + capacitors on output. Fixed 24dB obtain, onboard trim potentiometer for modifying input quantity. Thermal and quick-circuit/over-present safety Small existing draw: 4mA quiescent and .5mA in shutdown (because of to pullup resistor on SD pin) Be aware: The terminal block provided with your product may well be blue or black.

This tremendous tiny mono amplifier is astonishingly powerful – capable to deliver up to 2.5 Watts into 4-8 ohm impedance speakers. Inside the miniature chip is a class D controller, in a position to run from 2.0V-5.5VDC.
Considering the fact that the amp is a course D, its extremely effective (above 90% efficient when driving an 8Ω speaker at around 50 percent a Watt) – earning it best for moveable and battery-driven projects. It has developed in thermal and around-present-day defense but we could barely inform it bought hot. There is even a quantity trim pot so you can alter the quantity on the board down from the default 24dB obtain. This board is a welcome enhance to primary “LM386” amps!
The A+ and A- inputs of the amplifier go by 1.0uF capacitors, so they are fully ‘differential’ – if you do not have differential outputs, basically tie the Audio- pin to ground. The output is “Bridge Tied” – that usually means the output pins hook up specifically to the speaker pins, no link to ground.
Comes with a thoroughly assembled and examined breakout board. We also include things like header to plug it into a breadboard and a 3.5mm screw-terminal blocks so you can simply attach/detach your speaker. You will be ready to rock in 15 minutes! Speaker is not included, use any 4 ohm or higher impedance speaker.
