The Story
The INMP441 is a high-performance, low-power digital output omnidirectional MEMS microphone with a bottom port. It integrates a MEMS sensor, signal conditioning, ADC, anti-aliasing filter, and a 24-bit I2S interface for direct connection to digital processors like DSPs and microcontrollers. With a high SNR of 61 dBA and flat frequency response from 60Hz to 15kHz, it delivers clear, natural sound for near-field applications.
