With sound sources such as a normal speaking voice a few feet away from the microphone, the AUD output signal will be at about 200mV peak-to-peak. Also note, this low profile microphone has its port on the bottom side, so the microphone can be mounted flush to the outer surface of your enclosure. This microphone is omni-directional, which means it does a good job of picking up sound sources from all directions.\u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/learn.sparkfun.com\/tutorials\/analog-mems-microphone-breakout---sph8878lr5h-1-hookup-guide?_ga=2.139789232.286643215.1647882958-711853578.1634823988\" target=\"_blank\" rel=\"noopener noreferrer\"\u003eGet started with the Analog MEMS Microphone Breakout Hookup Guide\u003c\/a\u003e\u003c\/p\u003e\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eSupply Voltage: \u003cstrong\u003e2.3-3.6V\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003eAverage Current Consumption: \u003cstrong\u003e265µA\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003eFrequency Range: 7Hz-36kHz\u003c\/li\u003e\n\u003cli\u003eSignal-to-Noise Ratio: 66dBV\/Pa\u003c\/li\u003e\n\u003cli\u003eSensitivity: ~44dBV\/Pa (Single-Ended Mode)\u003c\/li\u003e\n\u003cli\u003e-3dB Roll Off at 7Hz \/ +3dB Flatness at 36kHz\u003c\/li\u003e\n\u003cli\u003eAcoustic Overload Point: 134dB SPL\u003c\/li\u003e\n\u003cli\u003eOPA344 provides 600Ω output impedance\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eDocuments\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/cdn.sparkfun.com\/assets\/7\/5\/6\/e\/d\/SparkFun_Analog_MEMS_Microphone_Breakout_SPH8878LR5H-1.pdf\" target=\"_blank\" rel=\"noopener noreferrer\"\u003eSchematic\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/cdn.sparkfun.com\/assets\/4\/a\/f\/6\/b\/SparkFun_Analog_MEMS_Microphone_Breakout_SPH8878LR5H-1.zip\" target=\"_blank\" rel=\"noopener noreferrer\"\u003eEagle Files\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/cdn.sparkfun.com\/assets\/c\/e\/3\/6\/4\/SparkFun_Analog_MEMS_Microphone_Breakout_SPH8878LR5H-1_Dimensions.png\" target=\"_blank\" rel=\"noopener noreferrer\"\u003eBoard Dimensions\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/learn.sparkfun.com\/tutorials\/analog-mems-microphone-breakout---sph8878lr5h-1-hookup-guide?_ga=2.131450636.286643215.1647882958-711853578.1634823988\" target=\"_blank\" rel=\"noopener noreferrer\"\u003eHookup Guide\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\n\u003ca href=\"https:\/\/cdn.sparkfun.com\/assets\/0\/5\/8\/b\/1\/SPH8878LR5H-1_Lovato_DS.pdf\" target=\"_blank\" rel=\"noopener noreferrer\"\u003eDatasheet\u003c\/a\u003e (SPH8878LR5H-1)\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/github.com\/sparkfun\/SparkFun_Analog_MEMS_Microphone_Breakout_SPH8878LR5H-1\" target=\"_blank\" rel=\"noopener noreferrer\"\u003eGitHub Hardware Repo\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Sparkfun","offers":[{"title":"Default Title","offer_id":39802933641299,"sku":"BOB-19389","price":6.95,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0174\/1800\/products\/19389-SparkFun_Analog_MEMS_Microphone_Breakout_-_SPH8878LR5H-1-01.jpg?v=1648049386","url":"https:\/\/shop.pimoroni.com\/en-eu\/products\/sparkfun-analog-mems-microphone-breakout-sph8878lr5h-1","provider":"Pimoroni Ltd","version":"1.0","type":"link"}
