INMP411 Omnidirectional Microphone with Bottom Port and Analog Output GENERAL DESCRIPTION APPLICATIONS The INMP411* is a high performance, high SPL, low noise, low Fire and Safety Radios power, analog output bottom ported, omnidirectional MEMS Safety Masks microphone. The INMP411 consists of a MEMS microphone Tablet Computers Teleconferencing Systems element and an impedance converter amplifier. The INMP411 Studio Microphones sensitivity specification makes it an excellent choice for near- Security and Surveillance field applications. The INMP411 is pin compatible with the INMP401 microphone, providing an easy upgrade path. FEATURES The INMP411 has a linear response up to 131 dB SPL. It offers high SNR and extended wideband frequency response 4.72 3.76 1.0 mm Surface-Mount Package resulting in natural sound with high intelligibility. Low current High 131 dB SPL Acoustic Overload Point consumption enables long battery life for portable Sensitivity of 46 dBV applications. 2 dB Sensitivity Tolerance Omnidirectional Response The INMP411 is available in a 4.72 3.76 1.0 mm surface- High SNR of 62 dBA mount package. It is reflow solder compatible with no Extended Frequency Response from 28 Hz to 20 kHz sensitivity degradation. Low Current Consumption: <250 A *Protected by U.S. Patents 7,449,356 7,825,484 7,885,423 and 7,961,897. Single-Ended Analog Output Other patents are pending.
