Omnidirectional Microphone Module (INMP441) - High Precision I2S (D49)
The INMP441 is a high-performance omnidirectional MEMS microphone with a built-in I²S digital interface, delivering 24-bit high-precision audio data for crystal-clear voice and sound acquisition. Its connections are perfect for use with an Arduino or Raspberry Pi setup. With a high signal-to-noise ratio of 61 dBA and sensitivity of -26 dBFS, it captures nuanced audio with minimal distortion. Its flat frequency response from 60 Hz to 15 kHz ensures accurate reproduction across the vocal and acoustic range, while drawing just 1.4 mA of current, making it ideal for battery-powered applications.
The INMP441 features a compact 4.72 × 3.76 × 1 mm surface-mount package, supports both Sn/Pb and lead-free solder processes, and is fully RoHS/WEEE compliant. With a power supply rejection (PSR) of -75 dBFS, it's well-suited for noise-sensitive embedded systems, IoT audio applications, and voice interfaces.
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
