INMP441 Omnidirectional Microphone Module I2S Interface Low Power MEMS Digital Output Sensor Module Soldered Pin

INMP441 Omnidirectional Microphone Module I2S Interface Low Power MEMS Digital Output Sensor Module Soldered Pin Description

1. High-Performance, Low-Power Digital MEMS Microphone: The INMP441 digital output sensor module is a high-performance, low-power, digital output, omnidirectional MEMS microphone with a bottom port.
2. Complete INMP441 Solution with Industry-Standard 24-bit I²S Interface: The INMP441 solution includes a MEMS sensor, signal conditioning, analog-to-digital converter, anti-aliasing filter, power management, and an industry-standard 24-bit I2;S interface.
3. Direct Connection to Digital Processors: Thanks to the I²S interface, the INMP441 can be directly connected to digital processors such as DSPs and microcontrollers without the need for audio codecs in the system.
4. Clear and Natural Sound with High SNR: The INMP441 digital output sensor module features a flat wideband frequency response, resulting in natural sound reproduction with high clarity. Its high signal-to-noise ratio (SNR) makes it a perfect choice for near-field applications.

Product Features:
1. Digital I²S interface with high-precision 24-bit data
2. High signal-to-noise ratio of 61 dBA
3. High sensitivity -26 dBFS
4. Stable frequency response from 60 Hz to 15 kHz
5. Low power consumption: low current consumption of 1.4 mA
6. High PSR: -75 dBFS

Interface Definitions:
SCK: Serial data clock for the I²S interface
