INMP441 Omnidirectional Microphone Modules I2S Interface MEMS High Precision Sensor Low Power Suitable for ESP32 6PIN

Product Description：

The INMP441 is a high performance, low power, digital output, omnidirectional MEMS microphone with bottom port. The complete INMP441 solution consists of a MEMS transducer, signal composition conditioning, analog-to-digital converter, anti-alias filter, power management, and an industry-standard 24-bit I2S interface that allows the INMP441 to connect directly to digital processors such as DSPs and microcontrollers without the need for the audio codec used in the system. The INMP441 has a high signal-to-noise ratio and is an excellent choice for near-field applications. The INMP441 has a flat broadband frequency response resulting in natural sounding high definition.

Product Features:

1. Digital I2S interface with high precision 24-bit data

2. High signal-to-noise ratio of 61 dBA

3. High sensitivity of -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 definition:

SCK : Serial data clock for I2S interface

WS : Serial data word selection for I2S interface

L/R : Left/Right channel selection.

When set low, the microphone outputs the signal in the left channel of the I2S frame.

When set high, the microphone outputs the signal in the right channel

SD: Serial data output of the I2S interface.

VCC: Input power supply, 1.8V to 3.3V.

GND: Power ground
