The SparkFun I2<\/sup>S Audio Breakout board uses the MAX98357A digital to analog converter (DAC), which converts I2<\/sup>S (not be confused with I2<\/sup>C) audio to an analog signal to drive speakers. The I2<\/sup>S Audio Breakout converts the digital audio signals using the I2<\/sup>S standard to an analog signal and amplifies the signal using a class D amplifier which can deliver up to 3.2W of power into a 4\u2126 load. The board can be configured to output only the left channel audio, right channel, or both.<\/p>\n\n The SparkFun I2<\/sup>S Audio Breakout board is fairly simple, requiring only a few pin connections to get it up and working. By default the board is configured in \u201cmono\u201d operation, meaning the left and right signals are combined together to drive a single speaker. If you want a separate speaker for the left and right audio channels you\u2019ll need to cut the mono jumper. In addition to being able to select the audio channel output, the gain can also be configured in a few ways. The gain of the amplifier can be configured from as low as +3dB to as high as +15dB. While the channel selection can be configured on board, the gain however is controlled externally using the gain pin. By default, the board is configured for +9dB, but can be easily changed!<\/p>\n\n
