INMP401 Omnidirectional Microphone with Bottom Port and Analog Output GENERAL DESCRIPTION The INMP401* is a high-quality, high-performance, lowpower, analog-output bottom-ported omnidirectional MEMS microphone. The INMP401 consists of a MEMS microphone element, an impedance converter, and an output amplifier. The INMP401 sensitivity specification makes it an excellent choice for near-field applications. The INMP401 has a wideband frequency response, resulting in natural sound with high intelligibility. The specially designed low frequency cutoff reduces wind noise. Its low current consumption enables long battery life for portable applications.
