INMP441: Omnidirectional Digital I2S Microphone
The INMP441 is a high-performance, low-power, omnidirectional MEMS microphone with a bottom port and a digital I2S interface. It provides a complete solution for audio sensing, integrating a sensing element, a micro-electrical-mechanical system (MEMS), and an integrated circuit for high-fidelity signal conversion.
- Direct Digital Output: Connects directly to R1BBIT controllers via I2S, removing the need for an analog-to-digital converter.
- Flat Frequency Response: Provides a natural sound across a wide range of frequencies.
- High Signal-to-Noise Ratio (SNR): 61 dBA for clear, intelligible audio capture.
- Low Consumption: Ideal for battery-powered smart-home devices.
