The complete INMP441 consists of MEMS sensors, signal conditioning, analog-to-digital converters, anti-aliasing filters, power management, and an industry-standard 24-bit I²S interface. The i2s interface allows the INMP441 to connect directly to digital processors such as DSPS and microcontrollers without using the audio codecs used in the system.

Digital I²S interface, high precision 24-bit data
High SNR of 61 dBA;
High sensitivity -26 dBFS;

Stable frequency response from 60hz to 15khz;
Low power consumption: low current consumption 1.4mA;
High PSR: -75 dBFS;
SD: I²S interface serial data output;
VCC: Input power supply, 1.8V ~ 3.3V;
GND: Power grounding.

Interface definition:
SCK: Serial data clock for I²S interface
WS: Serial data word select my ²S interface
L/R: Select the left and right channels.

When set to low power level, the microphone outputs the signal in the left channel of the I²S frame. When set to high power level, the microphone outputs the signal in the correct channel
