{"product_id":"1815-ma13","title":"PROPC-106300 - ADAFRUIT 1063 ELECTRET MICROPHON AMPLIFIER MAX4466","description":"\u003cp\u003eElectret Microphone Amplifier  MAX4466 with Adjustable Gain\u003c\/p\u003e\n\n\u003cp\u003eAdd an ear to your project with this welldesigned electret microphone amplifier. This fully assembled and tested board comes with a 2020KHz electret microphone soldered on. For the amplification  we use the Maxim MAX4466  an opamp 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!\u003c\/p\u003e\n\n\u003cp\u003eThis breakout is best used for projects such as voice changers  audio recording\/sampling  and audioreactive 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. That'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 railtorail so if the sounds get loud  the output can go up to 5Vpp!\u003c\/p\u003e\n\n\u003cp\u003eUsing it is simple: connect GND to ground  VCC to 2.45VDC. For the best performance  use the quietest supply available (on an Arduino  this would be the 3.3V supply). The 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 (it is DC coupled). If the audio equipment you're using requires AC coupled audio  place a 100uF capacitor between the output pin and the input of your device. If you're connecting to an audio amplifier that has differential inputs or includes decoupling capacitors  the 100uF cap is not required.\u003c\/p\u003e","brand":"Generic","offers":[{"title":"Default Title","offer_id":44854851403845,"sku":"274485-1815-MA13","price":8.95,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0102\/6644\/3834\/files\/1815-MA13.jpg?v=1775737972","url":"https:\/\/shop.sayal.com\/products\/1815-ma13","provider":"SAYAL Electronics","version":"1.0","type":"link"}
