The ADMP401 is a high-quality, low-cost, low-power analog output omnidirectional MEMS microphone located at the bottom port. The ADMP401 includes a MEMS microphone element, impedance converter and an output amplifier. The ADMP401 sensitivity makes it the best choice for near field and far field applications. The ADMP401 has a high signal-to-noise ratio and broadband flat frequency response, resulting in naturally high sound clarity. Low current consumption can extend battery life for portable applications. The built-in particle filter provides high reliability.
