If you're looking for an easy and low cost way to get your digital sound files bumpin' then the\u003cstrong\u003eMAX98357 I2S Amp Breakout\u003c\/strong\u003eis for you. It takes standard I2S digital audio input and, not only decodes it into analog, but also amplifies it directly into a speaker. Perfect for adding compact amplified sound, it takes 2 breakouts (I2S DAC + Amp) and combines them into one.\u003c\/p\u003e\n\u003cp style=\"line-height:inherit;margin:0px 0px 12.5px;margin-bottom:12.5px;margin-top:0px;margin-left:0px;margin-right:0px;box-sizing:border-box\"\u003eI2S (not to be confused with I2C) in a digital sound protocol that is used on circuit boards to pass audio data around. Many high end chips and processors manage all of the audio in digital I2S format. Then, to input or output data, three or four pins are used (data in, data out, bit clock and left-right channel select). Usually, for audio devices, there's a DAC chip that will take I2S in and convert it to analog that can drive a headphone.\u003c\/p\u003e\n\u003cp style=\"line-height:inherit;margin:0px 0px 12.5px;margin-bottom:12.5px;margin-top:0px;margin-left:0px;margin-right:0px;box-sizing:border-box\"\u003eThis small mono amplifier is surprisingly powerful - able to deliver 3.2 Watts of power into a 4 ohm impedance speaker (5V power @ 10% THD). Inside the miniature chip is a class D controller, able to run from 2.7V-5.5VDC. Since the amp is a class D, it's incredibly efficient - 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.\u003c\/p\u003e\n\u003cp style=\"line-height:inherit;margin:0px 0px 12.5px;margin-bottom:12.5px;margin-top:0px;margin-left:0px;margin-right:0px;box-sizing:border-box\"\u003eThe audio input is I2S standard, you can use 3.3V or 5V logic data. The outputs are \"Bridge Tied\" - that means they connect directly to the outputs, no connection to ground. The output is a ~300KHz 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.\u003c\/p\u003e\n\u003cdiv style=\"box-sizing:border-box\"\u003e\n\u003cp style=\"line-height:inherit;margin:0px 0px 12.5px;margin-bottom:12.5px;margin-top:0px;margin-left:0px;margin-right:0px;box-sizing:border-box\"\u003eThere's a Gain pin that can be manipulated to change the gain. By default, the amp will give you 9dB of gain. By connecting a pullup or pull down resistor, or wiring directly, the Gain pin can be set up to give 3dB, 6dB, 9dB, 12dB or 15dB.\u003c\/p\u003e\n\u003cp style=\"line-height:inherit;margin:0px 0px 12.5px;margin-bottom:12.5px;margin-top:0px;margin-left:0px;margin-right:0px;box-sizing:border-box\"\u003eThe ShutDown\/Mode pin can be used to put the chip in shutdown or set up which I2S audio channel is piped to the speaker. By default, the amp will output (L+R)\/2 stereo mix into mono out. By adding a resistor, you can change it to be just left or just right output\u003c\/p\u003e\n\u003cp style=\"line-height:inherit;margin:0px 0px
