The complete INMP441 solution consists of a MEMS sensor, signal composition conditioning, analog-to-digital converter, anti-aliasing filter, power management and industry standard 24-bit I2S interface. The I2S interface allows INMP441 to connect directly to digital processors, such as DSPs and microcontrollers, without the need for the audio codec used in the system. INMP441 has a high signal-to-noise ratio and is an excellent choice for near-field applications. INMP441 has a flat broadband frequency response, resulting in high definition of natural sound.
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 definition:
SCK: Serial data clock of I2S interface
WS: Serial data word selection for I2S interface
L/R: left/right channel selection.
When set to low level, the microphone outputs signals on the left channel of the I2S frame.
When set to high level, the microphone outputs the signal on the right channel
SD: Serial data output of I2S interface.
VCC: Input power, 1.8V to 3.3V.
GND: power ground
