Overview

This incredibly small stereo amplifier is surprisingly powerful - able to deliver 2 x 3.7W

channels into 3 ohm impedance speakers. Inside the miniature chip is a class D controller,

able to run from 2.7V-5.5VDC. Since the amp is a class D, its incredibly efficient (over 90%

efficient when driving an 8Ω speaker at over a Watt).

This amplifier is perfect for portable and battery-powered projects. It has built in thermal and

over-current protection, but you really have to drive it hard before it even gets warm! This

board is a welcome upgrade to basic "LM386" amps!
