For the amplification, we use the Maxim MAX4466, an op-amp specifically designed for this delicate task; The amplifier has excellent power supply noise rejection, so this amplifier sounds really good and isn’t nearly as noisy or scratchy as other mic amp breakouts we’ve tried!\u003cbr\u003e\u003cbr\u003eThis MAX4466 Electret Microphone Amplifier with an Adjustable Gain Module is best used for projects such as voice changes; audio recording\/sampling, and audio-reactive projects that use FFT. On the back, we include a small trimmer pot to adjust the gain. You can set the gain from 25x to 125x.\u003cbr\u003e\u003cbr\u003eThat’s down to be about 200mVpp (for normal speaking volume about 6″ away) which is good for attaching to something that expects ‘line level’ input without clipping, or up to about 1Vpp, ideal for reading from a microcontroller ADC. The output is rail-to-rail so if the sounds get loud, the output can go up to 5Vpp.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eHow to Use :\u003c\/strong\u003e Connect GND to ground, VCC to 2.4-5VDC.\u003cbr\u003e\u003cbr\u003eThe audio waveform will come out of the OUT pin. The output will have a DC bias of VCC\/2 so when it's perfectly quiet; the voltage will be a steady VCC\/2 volt (DC couple).\u003cbr\u003e\u003cbr\u003eIf the audio equipment you’re using requires AC coupled audio; place a 100uF capacitor between the output pin and the input of your device.\u003cbr\u003e\u003cbr\u003eIf you’re connecting to an audio amplifier that has differential inputs or includes decoupling capacitors; the 100uF cap is not required.\u003cbr\u003e\u003cbr\u003eThe output pin is not designed to drive speakers or anything but the smallest in-ear headphones- you’ll need an audio amplifier (such as a 3.7W stereo amp)\u003cbr\u003e\u003cbr\u003eIf you want to connect the amp directly to speakers. If you’re connecting to a microcontroller pin, you don’t need an amplifier or decoupling capacitor; connect the OUT pin directly to the microcontroller ADC pin.\u003cbr\u003e\u003cbr\u003eFor audio-reactive projects; we suggest using an FFT driver library that can take the audio input and ‘translate’ it into frequencies.\u003c\/div\u003e\n\u003cdiv class=\"product_info\"\u003e\n\u003ch3 class=\"sing--sub-heading\"\u003eTechnical Details\u003c\/h3\u003e\n\u003cdiv id=\"p_info\"\u003e\n\u003cul class=\"pro-ds\"\u003e\n\u003cli\u003eInput Current: 24μA\u003c\/li\u003e\n\u003cli\u003eGain Bandwidth Product (GBP): 600kHz\u003c\/li\u003e\n\u003cli\u003eGain: 20dB\u003c\/li\u003e\n\u003cli\u003eDimensions (L x W x H): 20 x 14 x 8 mm\u003c\/li\u003e\n\u003cli\u003eWeight:1g\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"product_info\"\u003e\n\u003ch3 class=\"sing--sub-heading\"\u003eFeatures\u003c\/h3\u003e\n\u003cdiv id=\"p_info\"\u003e\n\u003cul class=\"pro-ds\"\u003e\n\u003cli\u003eSupply Voltage Operation: 2.4V to +5.5V\u003c\/li\u003e\n\u003cli\u003e5nA Complete Shutdown (MAX4467\/MAX4468)\u003c\/li\u003e\n\u003cli\u003ePower-Supply Rejection Ratio: 112dB\u003c\/li\u003e\n\u003cli\u003eCommon-Mode Rejection Ratio: 126dB\u003c\/li\u003e\n\u003cli\u003eHigh AVOL: 125dB (RL = 100kΩ)\u003c\/li\u003e\n\u003cli\u003eRail-to-Rail Outputs\u003c\/li\u003e\n\u003cli\u003eLow 24µA Quiescent Supply Current\u003c\/li\u003e\n\u003cli\u003eGain Bandwidth Product: 200kHz (MAX4465\/MAX4467\/MAX4469)\u003c\/li\u003e\n\u003cli\u003eGain Bandwidth Product: 600kHz AV ≥ 5 (MAX4466\/MAX4468)\u003c\/li\u003e\n\u003cli\u003eSpace-Saving Packages: 5-Pin SC70 (MAX4465\/MAX4466)\u003c\/li\u003e\n\u003cli\u003eSpace-Saving Packages: 8-Pin SOT23 (MAX4467\/MAX4468\/MAX4469)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"product_info\"\u003e\n\u003ch2 class=\"sing--sub-heading\"\u003e\u003cspan style=\"font-size: 18.72px;\"\u003eApplications :\u003c\/span\u003e\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eAudio signal amplification for microcontrollers\u003c\/li\u003e\n\u003cli\u003eVoice and sound detection projects\u003c\/li\u003e\n\u003cli\u003eDIY audio recording and processing\u003c\/li\u003e\n\u003cli\u003eSpeech recognition and voice control applications\u003c\/li\u003e\n\u003cli\u003eNoise monitoring and environmental sound analysis\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"product_info\"\u003e\n\u003ch3 class=\"sing--sub-heading\"\u003ePhysical Attributes\u003c\/h3\u003e\n\u003cdiv id=\"p_info\"\u003e\n\u003cul class=\"pro-ds\"\u003e\n\u003cli\u003eDimensions: 20x14x8mm\u003c\/li\u003e\n\u003cli\u003eWeight: approx. 1g\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"product_info\"\u003e\n\u003ch3 class=\"sing--sub-heading\"\u003ePackage Includes\u003c\/h3\u003e\n\u003cdiv id=\"p_info\"\u003e\n\u003cul class=\"pro-ds ls-n\"\u003e\n\u003cli\u003e1 x MAX4466 Electret Microphone Amplifier with Adjustable Gain Module\u003c\/li\u003e\n\u003cli\u003e1 x Header Set (Without Soldered)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"KitsGuru","offers":[{"title":"Default Title","offer_id":44670455808252,"sku":"KG1113","price":109.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0587\/2130\/4757\/files\/GY-MAX4466SoundSensorModuleMAX4466MicrophonePreamplifier.jpg?v=1742297420","url":"https:\/\/kitsguru.com\/es\/products\/gy-max4466-sound-sensor-module-max4466-microphone-preamplifier-provider","provider":"KitsGuru","version":"1.0","type":"link"}
