Product Features:

1. High-performance digital I²S output, compatible with INMP441 for seamless system integration.

2. 24-bit high-precision data delivers clear audio signals and natural sound reproduction.

3. High signal-to-noise ratio effectively reduces background noise interference.

4. High sensitivity precisely captures near-field audio details.

5. Wide frequency response (60Hz–15kHz) suits diverse voice capture scenarios.

Product Description:

This sensor is a high-performance, low-power, digital-output omnidirectional MEMS microphone with a bottom-port configuration. Compatible with INMP441, it comprises a MEMS sensor, signal conditioning circuitry, an analogue-to-digital converter, an anti-aliasing filter, power management, and an industry-standard 24-bit I²S interface. The I²S interface enables direct connection to digital processors such as DSPs and microcontrollers without requiring an audio codec within the system. Featuring a high signal-to-noise ratio, it is an excellent choice for near-field applications. Its flat, broadband frequency response delivers natural sound with high clarity.
