   "description": "All in one digital audio amp breakout board that works incredibly well with the Raspberry Pi! If you're looking for an easy and low cost way to get you digital sound files bumpin' then the MAX08357 I2S Amp Breakout is 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. There'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. The 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 Works great with Raspberry Pi, Arduino Zero, and any other microcontroller or microcomputer with I2S audio outputs Specifications Output Power: 3.2W at 4Ω, 10% THD, 1.8W at 8Ω, 10% THD, with 5V supply PSRR: 77 dB typ @ 1KHz I2S sample rates from 8kHz to 96kHz No MCLK required Click + Pop reduction Five pin-selectable gains: 3dB, 6dB, 9dB, 12dB, 15dB Excellent click-and-pop suppression Thermal shutdown protection More Information Same Spec Items - SKU A-7425 Manufacturer OEM MPN A-7425 Can be used with -",
