PUI Audio wide-band MEMS microphones

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.

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 with a 20 Hz to 20 kHz response.

The top port AMM-2742-T-R also features a 2.75 x 1.85mm footprint, while standing only 0.9mm tall with a 20 Hz to 20 kHz frequency response.

Choose the ultra linear AMM-3738-B-R to capture sound the way it’s felt and heard from 20 Hz up to 10 kHz. A rising response to 20 kHz can also sense glass breaking.

For automotive applications, the AMM-3742-T-R has a dip in frequency response below 100 Hz for reduced wind and road noise.

Digital MEMS Microphones

PUI Audio’s digital 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 ideal for stereo recording!

The bottom port DMM-3526-B-R-digital microphone with PDM output features great sensitivity ( 26 dB) in a small 3.5 x 2.65 x 0.98mm package.

Choose the bottom port DMM-4026-B-R for completely flat frequency response down to 20 Hz in a 4 x 3 x 1mm form factor.

The top port DMM-4326-T-R allows for easy MEMS microphone integration into a product without the need for an acoustic hole in the PCBA.

For applications using I 2 S machine language, choose the DMM-4026-B-I2S-R . The I 2 S digital output makes microphone array integration a breeze!
