INTRIP INMP441 MEMS Microphone Plastic Design

Description

Product Overview

The INTRIP INMP441 is a high‑performance, low‑power digital MEMS microphone featuring an omnidirectional pickup pattern and a robust plastic enclosure. Housed in a thin 4.72 × 3.76 × 1 mm surface‑mount package, it delivers a flat wideband frequency response up to 15 kHz and a signal‑to‑noise ratio of 61 dB. Designed for I2S integration, the microphone includes serial data clock (SCK), word select (WS), and left/right channel (L/R) pins, making it ideal for tablet and laptop audio solutions. Its halide‑free construction meets stringent environmental standards while maintaining consistent sensitivity of 75 dB.

Usage

The INMP441 excels in teleconferencing systems, remote controls, gaming consoles, mobile devices, laptops, tablets, and security systems. Its compact size allows seamless embedding into slim devices, providing clear voice capture for voice assistants, in‑game chat, and video calls. The microphone’s low power draw suits battery‑operated gadgets, while its corded electric option ensures stable performance in stationary recording setups.
