Data Sheet Omnidirectional Microphone with Bottom Port and Analog Output ADMP401 FEATURES FUNCTIONAL BLOCK DIAGRAM 4.72 mm × 3.76 mm × 1.0 mm surface-mount package High SNR of 62 dBA Sensitivity of −42 dBV Flat frequency response from 100 Hz to 15 kHz OUTPUT AMPLIFIER OUTPUT Low current consumption of <250 μA Single-ended analog output High PSR of 70 dB Compatible with Sn/Pb and Pb-free solder processes RoHS/WEEE compliant E APPLICATIONS Smartphones and feature phones Teleconferencing systems T Digital video cameras Bluetooth headsets Video phones E Tablets GENERAL DESCRIPTION L The ADMP4011 is a high quality, high performance, 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 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 ADMP401 POWER VDD GND Figure 1. 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 ...
