INMP441 I2S Microphone MEMS I2S

INMP441 Omnidirectional Microphone Module MEMS I2S Interface Supports ESP32

INMP441 is a high performance, low power consumption, digital output, omnidirectional MEMS microphone with bottom port. The
The complete INMP441 solution consists of a MEMS sensor, signal composition conditioning, analog-to-digital converter, anti-aliasing filter, power management and industry standard 24-bit I2S interface. The I2S interface allows INMP441 to connect directly to digital processors, such as DSPs and microcontrollers, without the need for the audio codec used in the system. INMP441 has a high signal-to-noise ratio and is an excellent choice for near-field applications. INMP441 has a flat broadband frequency response, resulting in high definition of natural sound.
