DMM Omni-Directional Microphones

PUI Audio DMM Omni-Directional Microphones are digital MEMS microphones featuring PDM or I2S output, ±1dB tightly controlled sensitivity, and a wide frequency response. Available in multiple variants, these microphones offer both top and bottom acoustic port options to suit various integration needs. Designed for cloud-based voice applications and battery-powered devices, DMM microphones from PUI Audio simplify system design with built-in ADCs and digital outputs for seamless integration with DSPs and MCUs. Models such as the DMM-3537-2-B provide a high signal-to-noise ratio (up to 68dB), ensuring clear voice capture and strong noise performance, making them ideal for consumer electronics, smart devices, and voice assistants. Select models, such as the DMM-4326-T-WP-R, are IP57-rated with pre-applied waterproof mesh for added durability in harsh environments.
