The ADMP401 consists of a MEMS microphone element, an impedance converter, and an output amplifier. The O 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 OBS natural sound with high intelligibility. Low current consumption 07712-001 POWER VDD GND Figure 1. enables long battery life for portable applications. The ADMP401 plies with the TIA-920 standard, Telemunications 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 patible with no sensitivity degradation. The ADMP401 is halide free. 1 Protected by U.S. Patents 7,449,356; 7,825,484; 7,885,423; 7,961,897. Other patents are pending. Rev.
