NEW GUIDE: Adafruit STEMMA Audio Amp #STEMMA #Audio #AdafruitLearningSystem @Adafruit
TheAdafruit STEMMA Audio Ampis a 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, it’s very efficient (over 90% efficient when driving an 8Ω speaker at over half a Watt) – making it perfect for portable and battery-powered projects.
This board is a simplified version of our breadboard-friendly Adafruit Mono 2.5W Class D Audio Amplifier board. This version is designed to be ‘plug and play’ – with no soldering required. You can input the audio via the JST-PH 3 Pin connector – such as a pin header cable or one with alligator clips. The trade-off is that this board doesn’t have differential inputs, instead the audio inputs are referenced to the power/signal ground wire.
