The complete INMP441 solution consists of a MEMS sensor, signal conditioning, analog to digital converter, antialiasing filter, power management and 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. The INMP441 is a performance, low power, digital output, omnidirectional MEMS microphone with bottom port. Key benefits and features Digital 24bit I2S output for direct connection to DSPs and microcontrollers, simplifying system design and removing the need for a separate audio codec. Omnidirectional pickup pattern provides consistent sensitivity across directions, useful for general ambient sound capture and voice input. Bottom port configuration enables flexible mounting in compact enclosures and space constrained devices. Integrated signal conditioning, ADC, antialiasing filter and power management within a single solution to reduce board area and component count. Designed for low power operation, suitable for batterypowered and alwayson sensing applications.
