INMP441 is a powerful, energy-saving MEMS microphone with digital output, omnidirectional pickup and bottom connection. The complete INMP441 solution consists of a MEMS sensor, signal preparation, analog-digital, anti-aliasing filter, power management and an industry-standard 24-bit I2S interface. Through the I2S interface, the INMP441 can 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 DSPs and microcontrollers, reducing interface complexity and avoiding external codecs. - Omnidirectional sensing provides consistent voice capture in typical room conditions. - Bottom connection simplifies PCB layout and mounting. - Integrated signal path (sensor, ADC, anti-aliasing filter, power management) supports a compact, streamlined design. - 24-bit I2S interface delivers high-resolution data and broad compatibility with standard digital audio paths. Compatibility and performance - Industry-standard 24-bit I2S interface for easy integration with digital processors. - Digital output allows direct use with DSPs and microcontrollers. Use scenarios - Voice-controlled smart home devices and voice assistants. - Conference room and collaboration systems for clear audio capture. - Embedded IoT devices that require on-device audio sensing and command processing. Notes - The description reflects the INMP441 original specifications: a MEMS microphone with digital output, omnidirectional pickup, bottom connection, and a complete solution including signal conditioning, anti-aliasing, power management, and a 24-bit I2S interface.
