INMP405 Omnidirectional Microphone with Bottom Port and Analog Output The INMP405* is a high-quality, high-performance, low-power, analog-output bottom-ported omnidirectional MEMS microphone. The INMP405 consists of a MEMS microphone element, an impedance converter, and an output amplifier. The INMP405 sensitivity specification makes it an excellent choice for near-field applications. The INMP405 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. The INMP405 complies with the TIA-920 Telecommunications Telephone Terminal Equipment Transmission Requirements for Wideband Digital Wireline Telephones standard. The INMP405 is available in a miniature x mm surface-mount package. It is reflow solder compatible with no sensitivity degradation. The INMP405 is halide free.
