Anyhow, ST provides an evaluation board (codified MKI126Vx) allowing to interface the digital MEMS microphone to the common audio precision. Additionally, used in combination with the APWorkbench software, the ST microphone demo kit is the perfect assistant for basic measurements such as sensitivity, SNR, frequency response and THD.
