EYE ON NPI - IA611 SmartMic Audio Processor

Adafruit Industries

See this product on Digi-Key at https://www.digikey.com/short/t78q8n44 For this week's EYE ON NPI we're going to put a bug in your ear, with the Knowles IA611 SmartMic Audio Processor (https://www.digikey.com/en/product-highlight/k/knowles/ia611-smartmic-processor-xplained-pro-dev-kit) - perfect for making intelligent headsets, earpods or other low-power microphone devices. We've covered plenty of microphones before, including MEMS mics, and they've always been pretty straight forward: audio waves are detected, converted to a voltage, then piped out over PDM, I2S or analog. This microphone is particularly nifty, it can output I2S or PDM but it also has a built-in DSP processor that can detect keywords even in ultra-low sleep modes. This chip is specifically designed for making smart earpods, but would do well in any battery-powered product that needs voice activation Visit the Adafruit shop online - http://www.adafruit.com ----------------------------------------- LIVE CHAT IS HERE! http://adafru.it/discord Adafruit on Instagram: https://www.instagram.com/adafruit Subscribe to Adafruit on YouTube: http://adafru.it/subscribe New tutorials on the Adafruit Learning System: http://learn.adafruit.com/ -----------------------------------------
