InvenSense's 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, 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 and high sensitivity, making it an excellent choice for far 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 mm x 3.76 mm x 1 mm surface-mount package. It is reflow-solder compatible with no sensitivity degradation. The INMP441 is halide free.
