TDK launches 3 new SmartSound™ MEMS microphones

TDK Corporation introduces three new MEMS microphones as part of the SmartSound™ family of products for mobile, IoT and other consumer devices. Each of these high-performance microphones push the boundaries of microphone acoustic performance, providing advanced feature sets with very low power in small package footprints. The SmartSound family of MEMS microphones from TDK are designed for a multitude of applications in a variety of dynamic environments. High AOP, high SNR and wide dynamic range microphones are ideal for environments that shift from very quiet to very loud, such as far field voice pickup barge-in for Smart Speaker applications.

The T5919 is a multi-mode, low noise digital MEMS microphone in a small 3.5 × 2.65 × 0.98 mm bottom port package. The PIF filter is embedded in the microphone package, providing protection to particles and moisture. T5919 includes multiple modes of operation: High Quality, Low-Power (AlwaysOn), and Sleep. The T5919 microphone boasts high SNR in all operational modes. The microphone maintains 135 dB SPL AOP in High Quality Mode and 120 dB SPL AOP in Low-Power mode (more info).
