NEW GUIDE: Adafruit PAM8302 – Mono 2.5W Class D Audio Amplifier #AdafruitLearningSystem #Adafruit @adafruit

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 Adafruit PAM8302 guide has everything you need to get started with amplifying some speakers. There’s an overview, pinouts, and download resources.
