The INMP441 is a high-performance, low-power, digital-output, omnidirectional MEMS microphone module designed for advanced audio and voice recognition applications. It integrates a MEMS sensor, signal conditioning, an analog-to-digital converter (ADC), anti-aliasing filters, power management, and a standard 24-bit I²S interface, allowing seamless connection to digital processors without the need for an audio codec.

Key Features:

• Digital I²S interface with high-precision 24-bit data
• High Signal-to-Noise Ratio (SNR) of 61 dBA
• Sensitivity: -26 dBFS
• Flat frequency response from 60 Hz to 15 kHz
• Low current consumption of 1.4 mA
• High Power Supply Rejection (PSR) of -75 dBFS
• Compact surface-mount package: 4.72 × 3.76 × 1 mm
• RoHS/WEEE compliant
