INMP441 is a high-performance, low-power, digital output, omnidirectional MEMS microphone with a bottom port
The INMP441 module includes MEMS sensors, signal composition adjustment, analog-to-digital converters, anti-aliasing filters, power management, and an industry-standard 24-bit I2S interface
The I2S interface allows INMP441 to be directly connected to digital processors, such as DSPs and microcontrollers, without the need for audio codecs used in the system
The INMP441 has a high signal-to-noise ratio of 61dBA, making it an excellent choice for near-field applications
INMP441 has a flat broadband frequency response, resulting in high sound clarity
