Product Overview: The INMP441 is a high-performance, low-power, omnidirectional MEMS microphone with a digital output and a bottom port.
The complete INMP441 solution includes a MEMS sensor, signal conditioning system, analog-to-digital converter, anti-aliasing filter, power management system, and a standard 24-bit I²S interface.
The I²S interface allows the INMP441 to be directly connected to digital processors such as DSPs and microcontrollers, without requiring an audio codec.
The INMP441 offers a high signal-to-noise ratio and is an excellent choice for close-miking applications. The INMP441 provides a wideband, flat frequency response, ensuring natural, high-definition sound.
Product Features: 1. High-precision I2S digital interface (24-bit data); 2. High signal-to-noise ratio: 61 dBA
3. High sensitivity: -26 dBFS
4. Stable frequency response from 60 Hz to 15 kHz; 5. Low power consumption: 1.4 mA
6. High PSR: -75 dBFS. Interface definitions: SCK: Serial data clock for the I2S interface; WS: Serial data word selection for the I2S interface; L/R: Left/right channel selection. When low, the microphone transmits a signal on the left channel of the I2S frame. In its high state, it outputs a signal on the right channel; SD: Serial data output of the I2S interface. VCC: Power supply, 1.8V to 3.3V. GND: Ground. Connection to the ESP32: INMP441.
ESP32: SCK – GPIO14, SD – GPIO32, WS – GPIO15, L/R – GND, GND – GND, VDD – VDD3.3. Color: Black. Material: ABS. Package contents: 5 omnidirectional microphone modules. Only the above-mentioned contents are included. Note: The color of the item in the photo may slightly differ from the real thing due to lighting and your monitor settings. Please allow for a margin of error of +/- 1 to 3 cm.
