INMP441 is a performance, low power digital output omnidirectional MEMS microphone with bottom port. The complete INMP441 solution consists of a MEMS sensor, signal conditioning, analog to digital converter, anti aliasing filter, power management and industry standard 24 bit I2S interface. The I2S interface allows the INMP441 to be connected directly to digital processors such as DSPs and microcontrollers without the need for an audio codec for use in the system. Key benefits Digital output enables direct connection to digital processors with reduced noise and simplified signal routing Low power operation suitable for battery powered and portable devices Omnidirectional pickup provides consistent voice capture across angles Bottom port design supports acoustic performance and convenient mounting Integrated signal conditioning and anti aliasing filter simplify system design 24 bit I2S interface supports resolution audio data for voice capture Direct compatibility with DSPs and microcontrollers without an external codec Use scenarios Voice control and wake word sensing in consumer electronics and smart home devices Teleconferencing and collaboration equipment for clear voice capture in small to medium rooms Portable devices and IoT sensors that require compact, low power digital microphone inputs
