General Description

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.

Key Features

  • Digital I²S Interface with High-Precision 24-Bit Data.
  • High SNR of 61 dBA.
  • High Sensitivity of -26 dBFS.
  • Flat Frequency Response from 60 Hz to 15 kHz.
  • Low Current Consumption of 1.4 mA.
  • High PSR of -75 dBFS.
  • Small 4.72 × 3.76 × 1 mm Surface-Mount Package.
  • Compatible with Sn/Pb and Pb-Free Solder Processes.
  • RoHS/WEEE Compliant.
