{"title":"I2S MEMS Microphone Breakout - ICS-43434","handle":"adafruit-i2s-mems-microphone-breakout-ics-43434","url":"/products/adafruit-i2s-mems-microphone-breakout-ics-43434","description":"Add digital audio input to a capable microcontroller or single-board computer with this tiny breakout for the TDK ICS43434 I2S MEMS microphone. MEMS microphones detect sound like classic electret mics, but are much smaller and thinner, and this one outputs digital I2S audio rather than an analogue signal.The breakout provides the digital I2S signals you need: Clock, Data, and Left-Right/Word Select Clock. Your microcontroller or computer drives the clock and word-select lines, then reads the microphone data directly, so no analogue conversion stage is required.This is a single mono, bottom-ported microphone. The Select pin lets you choose whether it appears on the left or right channel, and two microphones can be paired for stereo by sharing Clock, WS, and Data while setting one Select pin low and the other high. It provides 24-bit output without firmware or driver configuration.It is intended for 1.6–3.6 V logic only and is not suitable for 5 V logic. It is best matched with boards that support I2S, such as Cortex M-series chips including SAMD21 and SAMD51, ESP32, RP2040 or RP2350, and single-board computers like the Raspberry Pi. The Adafruit guide includes code, libraries, wiring examples, CAD files, Fritzing files, and more.Specifications:Sensitivity: −26 dB FS ±1dBSNR High Performance Mode: 65 dBASNR Low Power Mode: 64 dBACurrent Draw High Performance Mode: 490 µACurrent Draw Low Power Mode: 230 µAMicrophone Acoustic Overload Point (AOP): 120 dB SPLSample Rate High Performance Mode: 23 ~ 51.6 kHzSample Rate Low Power Mode: 6.25 ~ 18.75 kHzUseful for general audio recording and sound detection projects where a clean digital microphone interface is preferred over an analogue mic.","vendor":"Adafruit","product_type":"Microphone Breakout","in_stock":true,"options":[],"variants":[{"id":16323,"title":"Default Title","sku":"AF-6049","mpn":"ADA6049","price":12.15,"on_sale":false,"in_stock":true,"available_quantity":100}]}
