Analog MEMS Microphones

PUI Audio is proud to release a line of premium, high-fidelity MEMS microphones that cover the entire audio band from 20 Hz up to 18 kHz — and up to 20 kHz on some models — while featuring industry-best unit-to-unit consistency ±1 dB across the entire frequency response.

Hit the ground running with MEMS microphones using PUI Audio's MEMS Application Guide!

AMM-2738-B-R

The bottom-port AMM-2738-B-R features a super-small 2.75 x 1.85mm footprint, while standing only 0.9mm tall for wearables, and a 20 Hz to 20 kHz response.
