The INMP404† is a high quality, low cost, low power, analog output bottom-ported omnidirectional MEMS microphone. The INMP404 consists of a MEMS microphone element, an impedance converter, and an output amplifier. The INMP404 sensitivity specification makes it an excellent choice for both near field and far field applications. The INMP404 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 INMP404 complies with the TIA-920 Telecommunications Telephone Terminal Equipment Transmission Requirements for Wideband Digital Wireline Telephones standard.
The INMP404 is available in an ultraminiature 3.35 mm × 2.50 mm × 0.88 mm surface-mount package. It is reflow solder compatible with no sensitivity degradation. The INMP404 is halide free.
