The ADMP401-1 is a high quality, low cost, low power analog output bottom-ported omnidirectional MEMS microphone. The ADMP401-1 consists of a MEMS microphone element and an output amplifier. The ADMP401-1 has a high SNR and high sensitivity, making it an excellent choice for far field applications. The ADMP401-1 has a flat wideband frequency response resulting in natural sound with high intelligibility. Low current consumption enables long battery life for portable applications. A built-in particle filter provides for high reliability. The ADMP401-1 is available in a thin 4.72 mm x 3.76 mm x 1.0 mm surface mount package. The ADMP401-1 is reflow solder compatible with no sensitivity degradation.
