INMP441 is a powerful, low-power MEMS microphone with a digital output, omnidirectional response, and a bottom-port design. The complete INMP441 solution includes the MEMS sensor, signal conditioning, analog-to-digital conversion, an anti-aliasing filter, power management, and a 24-bit I2S interface, all in an industry-standard package. Through the I2S interface, the INMP441 can be connected directly to digital processors such as DSPs and microcontrollers, without the need for an external audio codec in the system. Key benefits and attributes - Function: digital omnidirectional microphone with integrated signal chain and power management - Compatibility: direct I2S connection to DSPs and microcontrollers (no codec required) - Interface: 24-bit I2S, industry standard - Form factor: bottom-port design for versatile mounting - Performance: low power operation with integrated signal conditioning and anti-aliasing filter Use scenarios - Voice input for embedded devices, smart speakers, or voice-controlled appliances - Audio sensing in IoT sensors and wearable devices - Digital microphone input for robotics, drones, or industrial equipment requiring onboard DSP-based audio processing
