INMP441 is a high performance, low power, digital output, omnidirectional MEMS microphone with a bottom port. The complete INMP441 solution consists of a MEMS sensor, signal conditioning, analog-to-digital converter, anti-aliasing filter, power management and an 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 - Direct digital 24-bit I2S interface to DSPs and microcontrollers, eliminating the need for an external codec and simplifying system design. - Low power operation suitable for battery-powered devices and always-on voice capture. - Omnidirectional pickup with a bottom port enables flexible placement and enclosure integration. - Integrated MEMS sensor, signal conditioning, ADC and anti-aliasing filter in a compact form factor reduces BOM and board area, and improves signal integrity. - Reliable performance from MEMS technology in a standard I2S-ready package. Applications - Voice-enabled devices such as smart speakers, video conferencing systems, and headsets. - Consumer electronics and mobile devices requiring wake-word or voice input. - IoT and embedded solutions including security cameras, smart home hubs, and wearables with voice control.
