The ADMP401 consists ofa 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. A built-in particle filter provides for high reliability. The ADMP401 complies with the TIA-920 standard, Telecommunications Telephone Terminal Equipment Transmission Requirements for Wideband Digital Wireline Telephones.  \nThe 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.  \nFUNCTIONAL BLOCK DIAGRAM  \n\n| \u003Cbr>\u003Cbr>OUTPUT AMPLIFIER |  |  |  |  |\n| --- | --- | --- | --- | --- |\n| ADMP401 | POWER |  |  |  |\n|  |  |  |  |  |\n\nVDD GND  \nOUTPUT  \nFigure 1.  \n077 12-001  \nADMP401 Data Sheet  \nTABLE OF CONTENTS  \nFeatures .............................................................................................. 1  \nApplications ....................................................................................... 1  \nGeneral Description ......................................................................... 1  \nFunctional Block Diagram .............................................................. 1  \nRevision History ............................................................................... 2  \nSpecifications..................................................................................... 3  \nAbsolute Maximum Ratings............................................................ 4  \nESD Caution.................................................................................. 4  \nPin Configuration and Function Descriptions............................. 5  \nPrinted Circuit Board (PCB) Land Pattern Layout...................... 6  \nTypical Performance Characteristics ............................................. 7  \nREVISION HISTORY  \n1/12—Rev.
