SparkFun Analog MEMS Microphone Breakout - ICS-40180 - Elmwood Electronics

The SparkFun Analog MEMS Microphone Breakout makes it easy to work with the ICS-40180 analog microphone. This board features an OpAmp to bring the output of the microphone to a usable level, allowing you to plug directly into an ADC on a microcontroller or something like the SparkFun Spectrum Shield. In addition to amplifying the signal, the OpAmp adds a bias voltage of 1/2 VCC. The SparkFun breakout board includes an amplifier with a gain of 65 for the ICS-10480, which is more than sufficient for the microphones. The amplifier's AUD output will float at one-half Vcc when there is no sound. When held at arms length and talked into, the amplifier will produce a peak-to-peak output of about 200 mV. The board dimensions for the breakout are 0.50x 0.40. For a temporary connection, you can use IC hooks. Connect the Vcc port to 3.3V (or anything between 1.5 and 3.3V) and the GND port to ground. Connect the AUD port to an analog (ADC) input on a microcontroller. The SparkFun Analog MEMS Microphone Breakout makes it easy to work with the InvenSense ICS-40180 analog microphone.
