INMP401 Datasheet

The INMP401 is a high quality, low cost, low power 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 both near field and far field applications. The INMP401 has a high SNR and flat wideband frequency response, resulting in natural sound with high intelligibility. Low current consumption enables long battery life for portable applications. The INMP401 complies with the TIA-920 standard Telecommunications Telephone Terminal Equipment Transmission Requirements for Wideband Digital Wireline Telephones.

The INMP401 is available in a thin, 4.72 mm × 3.76 mm × 1.0 mm surface-mount package. It is reflow solder compatible with no sensitivity degradation. The INMP401 is halide free.
