Wideband MEMS Microphones

PUI Audio wideband MEMS microphones cover the full audio band from 20 Hz to 18 kHz, with some models extending to 20 kHz. These omnidirectional MEMS microphones provide ±1 dB unit-to-unit consistency tolerance across the entire frequency response. PUI Audio MEMS microphones are purpose-built for cloud-connected and battery-powered devices with sleep, low-power, and full-power modes for limiting current drain. Each microphone can be configured for left- or right-channel operation. The lineup includes analog and digital versions designed for a wide variety of applications.

The PUI Audio MEMS microphone portfolio, including select models manufactured in Korea, feature a specialized preamplification ASIC that provides high sensitivity and an excellent signal-to-noise ratio from a compact capacitive audio sensor. Designed for surface-mount assembly and high-temperature reflow processes, these microphones combine ultra-low current consumption with low distortion and a high acoustic overload point delivering exceptional dynamic range, reliability, and performance.

With these advancements, PUI Audio continues to offer competitive, high-performance MEMS microphone solutions for demanding audio applications.
