The component savings and simplified integration allowed by adding a digital I2S interface make these MEMS microphones ideal for audio recording and voice capture in space-constrained designs such as smartphones, tablets, smart home devices, wearables, and more.
Both microphones are omnidirectional and feature -26 dB sensitivity ratings, operating frequencies from 100 to 10,000 Hz, and current consumption of 400 microamps (µA). The CMM-3526D-261-I2S-TR further carries a signal-to-noise ratio (SNR) of 64 dBA, while the CMM-4030D-261-I2S-TR offers a SNR of 59 dBA.
As reflow solder compatible components, these digital I2S MEMS microphones afford designers additional flexibility where surface mount assembly is required. Both I2S models are also well suited for array applications used to perform beam forming and noise cancelation functions due to their tight sensitivity tolerances of ±1 dB.
The CMM-3526D-261-I2S-TR and CMM-4030D-261-I2S-TR are available immediately with prices starting at $1.59 per unit at 500 pieces through distribution. OEM pricing is available under request from CUI Devices.
