The multi-mode bottom-port MEMS microphone offers an exceptionally efficient 185µA ultra-low power mode, high SNR of 64.5 dB, and high acoustic overload point (AOP) of 120 dB in a 3.5×2.65×0.98mm package. The microphone’s AlwaysOn functionality in low-power mode enables immediate accessibility upon wake command.
TDK’s new T3902 microphone enables OEM partners to differentiate their product offerings by improving the consumer experience with reduced power consumption. This is especially critical to wearable and IoT designs where reduced board space and battery size are key factors to enabling a small form factor as well as providing a flexible and efficient (low power AlwaysOn) system design.
