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) - 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. This board is a welcome upgrade to basic \"LM386\" amps!\u003cbr style=\"box-sizing: border-box; -webkit-tap-highlight-color: transparent; outline: 0px;\"\u003eThe inputs of the amplifier go through 1.0uF capacitors, so they are fully 'differential' - if you don't have differential outputs, simply tie the R- and L- to ground. The outputs are \"Bridge Tied\" - that means they connect directly to the outputs, no connection to ground. The output is a 360KHz 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.\u003cbr style=\"box-sizing: border-box; -webkit-tap-highlight-color: transparent; outline: 0px;\"\u003eComes with a fully assembled and tested breakout board with 1.0uF input capacitors. We also include header to plug it into a breadboard, 3.5mm screw-terminal blocks so you can easily attach\/detach your speakers, and a 2x4 header + jumper to change the amplifier gain on the fly. You will be ready to rock in 15 minutes!Speakers are not included, use any 3ohm or greater impedance speakers.\u003cbr style=\"box-sizing: border-box; -webkit-tap-highlight-color: transparent; outline: 0px;\"\u003eOutput Power: 3.7W at 3Ω, 10% THD, 1.7W at 8Ω, 10% THD, with 5V Supply\u003cbr style=\"box-sizing: border-box; -webkit-tap-highlight-color: transparent; outline: 0px;\"\u003ePasses EMI limit unfiltered with up to 12 inches (30 cm) of speaker cable\u003cbr style=\"box-sizing: border-box; -webkit-tap-highlight-color: transparent; outline: 0px;\"\u003eHigh 83dB PSRR at 217Hz\u003cbr style=\"box-sizing: border-box; -webkit-tap-highlight-color: transparent; outline: 0px;\"\u003eSpread-Spectrum Modulation and Active Emissions Limiting\u003cbr style=\"box-sizing: border-box; -webkit-tap-highlight-color: transparent; outline: 0px;\"\u003eFive pin-selectable gains: 6dB, 9dB, 12dB, 15dB and 18dB.
