INMP441 Omnidirectional Microphone I2S Interface Digital Output Sensor Module

The INMP441 is a high-performance, low power, digital-output, omnidirectional MEMS microphone with a bottom port. The complete INMP441 solution consists of a MEMS sensor, signal conditioning, an analog-to-digital converter, anti-aliasing filters, power management, and an industry-standard 24-bit I²S interface. The I²S interface allows the INMP441 to connect directly to digital processors, such as DSPs and microcontrollers, without the need for an audio codec in the system.
The INMP441 has a high SNR, making it an excellent choice for near field applications. The INMP441 has a flat wideband frequency response, resulting in natural sound with high intelligibility.
The INMP441 is available in a thin 4.72 x 3.76 x 1 mm surface mount package. It is reflow- solder compatible with no sensitivity degradation. The INMP441 is halide free.
