GENERAL DESCRIPTION
The ADMP405 is a high quality, low cost, low power, analog output bottom-ported omnidirectional MEMS microphone. The ADMP405 consists of a MEMS microphone element, an impedance converter, and an output amplifier. The ADMP405 sensitivity specification makes it an excellent choice for both near field and far field applications. The ADMP405 has a high SNR and flat, wideband frequency response, resulting in natural sound with high intelligibility. The specially designed lowfrequency cutoff reduces wind noise. Low current consumption enables long battery life for portable applications. A built-in particle filter provides high reliability. The ADMP405 complies with the TIA-920 Telecommunications Telephone Terminal Equipment Transmission Requirements for Wideband Digital Wireline Telephones standard. The ADMP405 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 ADMP405 is halide free.
