The INMP441 is an omnidirectional pickup, low power, high performance MEMS microphone. The module integrates a MEMS sensor, signal conditioning, analog-to-digital converter, and anti-alias filter, all designed to deliver superior audio quality. The INMP441 module provides a complete audio capture solution with a built-in industry-standard 24-bit I²S interface, eliminating the need for additional audio codecs in the system. This makes it ideal for direct connection to digital processors such as DSPs and microcontrollers. Designed for digital efficiency, the INMP441 seamlessly connects via the I²S interface for direct integration with digital processors. This setup bypasses traditional audio codecs, simplifying the audio processing chain and improving system performance. Optimized for near-field applications, the INMP441 features a high signal-to-noise ratio and a flat, wide frequency response. This ensures that natural, high-definition sound is captured over a wide range of audio frequencies, making it the perfect choice for high-quality audio projects. The INMP441 is designed for developers looking for an efficient, high-quality audio solution. Its low power consumption and high accuracy make it an excellent choice for projects involving ESP32 microcontrollers, increasing project flexibility and audio fidelity.
