The INMP405 is a high quality, low cost, 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 both near field and far field applications. The INMP405 has a high SNR and flat, wideband frequency response, resulting in natural sound with high intelligibility. The specially designed low-frequency cutoff reduces wind noise. 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 an ultra-miniature 3.35 mm × 2.50 mm × 0.88 mm surface-mount package. It is reflow solder compatible with no sensitivity degradation. The INMP405 is halide free.
