The MM20 is a miniature, high- performance, low power, bottom port silicon
microphone with best SNR and extended dynamic range. Using Knowles’ proven high
performance MEMS technology, the MM20 consists of an acoustic sensor, a low noise
input buffer, and an output amplifier. These devices are suitable for applications where
excellent wideband audio performance and RF immunity are required.
