SparkFun Analog MEMS Microphone Breakout - ICS-40180

The SparkFun Analog MEMS Microphone Breakout - ICS-40180 is a user-friendly solution for those seeking to incorporate the InvenSense ICS-40180 analog microphone into their projects. It features an OpAmp that elevates the microphone's output to a usable level, enabling direct plug-in to an ADC on a microcontroller or a device like the SparkFun Spectrum Shield. The board also includes a bias voltage of half VCC, provided by the OpAmp.

The board is designed to amplify and deliver an output signal of around 200mV peak-to-peak when the sound source is a normal speaking voice a few feet away. The microphone is uniquely designed with a port on the bottom side, allowing for flush mounting to the outer surface of your enclosure. This low-profile microphone is also omni-directional, making it highly effective in picking up sound from all directions.

The SparkFun Analog MEMS Microphone Breakout - ICS-40180 is notable for its -3dB roll off at 60Hz and 19.7kHz. It operates comfortably within a supply voltage of 1.5VDC to 3.6VDC and can output a comfortable 40mW. The OPA344 provides 600Ω output impedance, and the device boasts an SNR of 65dBA.

In addition to the product itself, SparkFun provides comprehensive documentation to support users. This includes a schematic, Eagle Files, board dimensions, a hookup guide, a Fritzing Part, a datasheet for the ICS-40180, and a GitHub Hardware Repo. These resources ensure that users have all the information they need to effectively incorporate the SparkFun Analog MEMS Microphone Breakout - ICS-40180 into their projects.
