SPQ1410 Mems Microphone

JS-9003

Be the first to review this product

This tiny microphone board is a breakout board for SPQ1410 Omnidirectional Microphone with a Top Port and an Analog Output. The board includes an amplifying circuit with a gain of 67 that matches the bandwidth requirements of the SPQ1410. The amplifier's AUD output will float at one half Vcc when no sound is being picked up, and the amplifier produces a peak-to-peak output of about 200mV when the microphone is held at arms length and is being talked into at normal conversational volume levels. The convenient output voltage range of AUD means it can be directly connected to the ADC of a typical microcontroller.

The convenient output voltage range of AUD means it can be directly connected to the ADC of a typical microcontroller.

The breakout board pins have a 0.1" pitch, making the board compatible with:

  • standard 0.1" protoboards
  • breadboards
  • 0.1" male headers
  • 0.1" female headers


Features:

  • -3dB roll off at 100Hz and 15kHz
  • 1.5 to 3.6VDC supply voltage
  • Should comfortably output 40mW
  • Sensitivity of -42dBA
