Feature

●A complete INMP441 solution consists of MEMS sensor, signal adjustment, analog-digital converter, anti-aliasing filter, power management and industry standard 24-bit I2S interface. The I2S interface allows you to directly connect INMP441 to a digital processor such as DSP and microcontroller without the need for the audio codec used in your system
●Product Introduction:
●INMP441 is a high performance, low power, digital output, omnidirectional MEMS microphone with bottom port
●The INMP441 has a high signal to noise ratio and is ideal for close-up applications. INMP441 has a flat broadband frequency response which allows natural sound to be reproduced at high resolution
