The INMP441 is a complete MEMS microphone solution that combines a MEMS sensor, signal conditioning, an ADC, an anti-aliasing filter, power management, and a 24-bit I2S interface. The I2S interface lets the device connect directly to digital processors such as DSPs and microcontrollers without the need for an audio codec. Key benefits - Digital, low power, omnidirectional microphone with bottom port for flexible mounting - Integrated signal chain reduces external components and BOM - 24-bit I2S interface provides high-resolution audio data for processing - Direct compatibility with DSPs and microcontrollers without a codec Product overview - The INMP441 is a high performance, low power, digital output, omnidirectional MEMS microphone with bottom port Typical applications - Conference room and teleconferencing endpoints for clear voice capture - Voice-controlled smart home devices and embedded IoT systems - Portable handheld devices and wearables requiring high quality digital microphone input
