Feb. 6, 2023 /SemiMedia/ -- Infineon has recently announced the latest addition to its XENSIV™ MEMS microphone portfolio, the ultra-low power digital microphone IM69D128S.

The microphone is designed for applications which require high signal-to-noise ratio (SNR) / low microphone self-noise, long battery life, and high reliability. The unmatched SNR of 69 dB(A) enables a crystal-clear audio experience without compromising on battery life. Based on an advanced digital microphone ASIC, the IM69D128S sets a new benchmark in current consumption: 520 μA. This equals half the consumption of available models on the market with a similar performance. Additionally, IM69D128S masters the difficult task of switching between different power and performance profiles without any audible artifacts, that is glitches the user can hear. The PDM (pulse density modulation) microphone is based on Infineon’s latest Sealed Dual Membrane MEMS technology which delivers high ingress protection (IP57) at the microphone level.

Due to its ultra-low power consumption, IM69D128S is the perfect choice for hearable applications like true wireless earbuds, overear headsets, and hearing enhancement devices where battery life is key. Additionally, small size and high performance enable other space-critical applications like wearables, smartphone and IoT devices.

The PDM microphone IM69D128S can be ordered now. For more information, please visit www.infineon.com/mems.
