Infineon Introduced New PDM Microphone in a Small Package with Ultra-low Power Consumption

Update time : 2023-03-11 10:02:31

According to a recent study published by specialist technology company Omdia, Infineon's share of the microphone die manufacturing market rises to a staggering 45% by 2022.1 Infineon's deep experience in MEMS microphone design and volume production has enabled customers to create an unparalleled experience for consumers, leading to this impressive achievement.

Infineon's MEMS microphone development strategy covers the main building blocks MEMS, ASICs and packages for this sensor family. Infineon is therefore in complete control of the performance, quality and technical innovation of its products. Today, Infineon is launching its latest XENSIV™ MEMS microphone product, an ultra-low power digital microphone, the IM69D128S, based on its own technology.
This microphone is designed for applications requiring high signal-to-noise ratio (SNR)/low self-noise, long-lasting battery life and high reliability. Its excellent 69 dB(A) SNR delivers crystal clear sound quality without compromising battery life. With its advanced digital microphone ASIC, the IM69D128S sets a new benchmark in terms of power consumption: 520 uA, which is only half the power consumption of similarly performing products on the market. In addition, switching between power consumption and performance often results in abnormal noise (i.e. a harsh sound that can be heard by the user), which is perfectly avoided by the IM69D128S. This PDM (Pulse Density Modulation) microphone is capable of achieving up to IP57 protection on a semiconductor device, thanks to Infineon's latest sealed dual-diaphragm MEMS technology.
The ultra-low power IM69D128S is ideal for audio applications where battery life is critical, such as true wireless headsets, headphones and hearing enhancement devices. In addition, its small size and high performance make it suitable for space-critical applications such as wearable devices, smartphones and IoT devices.
