If you're looking for an easy and low cost way to get you digital sound files bumpin' then the MAX98357 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. \n\nI2S (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.\n\nThis 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. \n\nThe 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 wa...","shipping_methods":[{"name":"郵局掛號","fee":0,"currency":"TWD"},{"name":"7-ELEVEN取貨付款","fee":0,"currency":"TWD"},{"name":"7-ELEVEN取貨不付款","fee":0,"currency":"TWD"}],"lowest_shipping_fee":null,"payment_methods":["ATM轉帳","7-ELEVEN取貨付款"],"category_id":"2092072544","category_name":"其他電腦周邊","breadcrumb":[{"id":"23336","name":"電腦、平板與周邊","url":"/tw/%E9%9B%BB%E8%85%A6%E3%80%81%E5%B9%B3%E6%9D%BF%E8%88%87%E5%91%A8%E9%82%8A-23336-category.html"},{"id":"2092072522","name":"電腦/筆電周邊","url":"/tw/%E9%9B%BB%E8%85%A6-%E7%AD%86%E9%9B%BB%E5%91%A8%E9%82%8A-2092072522-category.html"},{"id":"2092072544","name":"其他電腦周邊","url":"/tw/%E5%85%B6%E4%BB%96%E9%9B%BB%E8%85%A6%E5%91%A8%E9%82%8A-2092072544-category.html"}],"view_count":0,"watch_count":1}
