INMP441 Omnidirectional Microphone Module.
INMP441 is a versatile MEMS microphone with high performance, low power consumption, digital outputs, and a bottom port. The complete INMP441 solution consists of the signal conditioning of the MEMS sensor, an analog-to-digital converter, an anti-aliasing filter, power management, and a 24-bit interface I²S industry standard.
The I²S interface of the INMP441 can be connected directly without using the audio codecs used in the system, such as a digital processor and microphone, for example, DSPs. The INMP441 is an excellent choice for high signal-to-noise ratio and near-field applications. The INMP441 has a flat band frequency response, resulting in a natural high sound definition.
