Analog Devices ADMP411 High SPL Microphone

Analog Devices ADMP411 High SPL Microphone

Analog Devices ADMP411 High SPL Microphone consists of a MEMS microphone element and an impedance converter amplifier. ADMP411 is a high-performance, omnidirectional device featuring low noise and low power. This ADI microphone's sensitivity specification makes it an excellent choice for both near field and far field applications. ADMP411 is pin-compatible with the ADMP401 microphone, providing an easy upgrade path. ADMP411 has a linear response up to 131dB SPL. It offers high SNR and extended wideband frequency response, resulting in natural sound with high intelligibility. Low current consumption enables long battery life for portable applications. EVAL-ADMP411Z-FLEX is a simple evaluation board that allows quick evaluation of the performance of ADMP411.
