AMM Omni-Directional Microphones

PUI Audio AMM Omni-Directional Microphones are surface-mount analog microphones with a wide frequency response, ±1dB tightly controlled sensitivity, and high acoustic overload points (AOP) up to 133dB. Designed with a compact footprint, these microphones from PUI Audio are ideal for smartphones, wearables, and other space-constrained applications. With low power consumption (typically 140µA to 160µA), AMM microphones are optimized for battery-sensitive designs. These devices also support frequency ranges capable of sensing events such as glass breaking and include options to reduce wind and road noise in automotive applications. Additionally, some models are IP57-rated and come with waterproof mesh pre-applied, ensuring reliability in harsh conditions and outdoor environments.

Wide-Band MEMS Microphones

PUI Audio Wide-Band MEMS Microphones cover the entire audio band from 20Hz to 18KHz, with up to 20kHz on some models. These PUI Audio omnidirectional MEMS Microphones provide unit-to-unit consistency of ±1dB tolerance across the entire frequency response. The lineup includes analog and digital versions for various applications, including smartphones, wearables, and cloud-based designs.
