Description

INMP441 MEMS High Precision Omnidirectional Microphone Module I2S

The INMP441 is a digital MEMS microphone that is omnidirectional and has a bottom port. It is designed to be high-performing and low-power, and the complete solution includes a MEMS sensor, signal conditioning, analog to digital converter, anti-aliasing filter, power management, and a 24-bit I2S interface that is industry-standard.

The I2S interface is especially useful because it allows for direct connection to digital processors such as microcontrollers and DSPs without the need for an audio codec. With a high signal-to-noise ratio, the INMP441 is a great option for applications in close proximity. It also has a flat wideband frequency response that results in natural and high-definition sound.

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 to low, the microphone outputs a signal on the left channel of the I2S frame.
When set to high level, the microphone outputs signals on the right channel
SD: Serial data output of the I2S interface.
VCC: Input power, 1.8V to 3.3V.
GND: power ground
