INMP401ACEZ-R0

INMP401 Omnidirectional Microphone with Bottom Port and Analog Output APPLICATIONS GENERAL DESCRIPTION * The INMP401 is a high-quality, high-performance, lowpower, analog-output bottom-ported omnidirectional MEMS microphone. The INMP401 consists of a MEMS microphone element, an impedance converter, and an output amplifier. The INMP401 sensitivity specification makes it an excellent choice for near-field applications. The INMP401 has a wideband frequency response, resulting in natural sound with high intelligibility. The specially designed low frequency cutoff reduces wind noise. Its low current consumption enables long battery life for portable applications. The INMP401 complies with the TIA-920 Telecommunications Telephone Terminal Equipment Transmission Requirements for Wideband Digital Wireline Telephones standard. The INMP401 is available in a 4.72 × 3.76 × 1.00 mm surfacemount package. It is reflow solder compatible with no sensitivity degradation. The INMP401 is halide free. • • • • • Mobile Devices Teleconferencing Systems Headsets Security Panels Intercom Devices FEATURES • • • • • • • • • 4.72 × 3.76 × 1.00 mm Surface-Mount Package SNR of 62 dBA Sensitivity of −42 dBV Flat Frequency Response from 60 Hz to 15 kHz Low Current Consumption:
