The INMP441 is a high performance, low power, digital output, omnidirectional MEMS microphone with a lower port. Most
The complete INMP441 solution consists of an MEMS sensor, signal conditioning, analog to digital converter, anti-aliasing filter, power management and industry standard 24-bit I2S interface. The I2S interface allows the inmp41 to be connected directly to digital processors such as DSPs and microcontrollers without requiring an audio codec for use 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 that causes a high definition of natural sound.

Interface description:
- 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 emits a signal on the left channel of the I2S frame.
- When set to high, the microphone will signal on the right channel
- SD: Serial data output of the I2S interface.
- VCC: input power, 1.8V to 3.3V.
- GND: power ground
