INMP441 Microphone Module - I2C Interface

INMP441 Microphone Module - I2C Interface

The INMP441 is a high-performance, low-power, digital output, omnidirectional MEMS microphone with bottom port. The complete INMP441 solution consists of a MEMS sensor, signal conditioning, analog-to-digital converter, anti-aliasing filter, power management, and an industry-standard 24-bit I2C interface. The I2C interface allows the INMP 441 to be directly connected to digital processors such as DSPs and microcontrollers without the need for an audio codec for use in the system. The module has a high signal-to-noise ratio and is an excellent choice for near-field applications. INMP441 has a flat wide-band frequency response resulting in high definition of natural sound.
