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, antialiasing filter, power management and an industry standard 24bit 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 Direct digital interface: 24bit I2S output enables connection to DSPs and microcontrollers without an external audio codec, simplifying the design and reducing component count. Low power, performance: optimized for energy efficiency while delivering clear audio capture. Omnidirectional bottomport design: suitable for flexible placement in devices and effective hands voice capture. Integrated signal path: MEMS sensor, ADC, antialiasing filter and power management are coordinated in a single solution, reducing external components and PCB area. Industry standard compatibility: I2S interface supports broad compatibility with common digital processors and development environments. Key attributes Function: digital omnidirectional MEMS microphone with bottom port and 24bit I2S output. Compatibility: connects directly to DSPs and microcontrollers via I2S without an audio codec.
