For the third year in a row, Infineon Technologies has successfully defended its position as a supplier of MEMS microphones. Furthermore, Infineon's market share increased to an impressive 45% as a bare die microphone manufacturer in 2021 – according to recent research published by technology expert Omdia.
This positive development is due to Infineon's long experience in MEMS microphone design and high-volume manufacturing, supporting customers to deliver an unparalleled consumer experience.
Infineon's MEMS microphone development strategy includes the core MEMS, ASIC and package building blocks for this family of sensors. For this reason, Infineon has full ownership of the performance, quality and technological innovation of its products.
Building on its know-how, Infineon now presents the latest addition to the XENSIV microphone product portfolio 
MEMS, the IM69D128S ultra-low power digital microphone.
The microphone is designed for applications that require high signal-to-noise ratio (SNR)/low microphone self-noise, long battery life, and high reliability. 69 dB(A) SNR allows for a crystal-clear audio experience without compromising battery life. Based on an advanced digital microphone ASIC, the IM69D128S sets a new benchmark in current consumption: 520 μA. This is equivalent to half the consumption of models available on the market with similar performance.
Furthermore, the IM69D128S masters the difficult task of switching between different power and performance profiles without any audible artifacts, i.e. glitches that the user can hear. The PDM (Pulse Density Modulation) microphone is based on Infineon's latest Sealed Dual Membrane MEMS technology, which offers high input protection (IP57) at the microphone level.
Due to its ultra-low power consumption, the IM69D128S is the perfect choice for hearing applications such as true wireless earbuds, earbuds, and hearing enhancement devices where battery life is critical. The small size and high performance also enable other space-critical applications, such as wearables, smartphones and IoT devices.
