Please visit the InvenSense ADMP401 product page for all technical support and sales information.
The ADMP401 is a high quality, low cost, low power analog output bottom-ported omnidirectional MEMS microphone. The ADMP401 consists of a MEMS microphone element, an impedance converter, and an output amplifier. The ADMP401 sensitivity specification makes it an excellent choice for both near field and far field applications. The ADMP401 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 ADMP401 complies with the TIA-920 standard Telecommunications Telephone Terminal Equipment Transmission Requirements for Wideband Digital Wireline Telephones.
The ADMP401 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 ADMP401 is halide free.
