Infineon Applied sciences AG has expanded its XENSIV MEMS microphone lineup with the introduction of the IM72D128V and IM69D129F, two progressive digital PDM microphones designed for distinctive audio efficiency, vitality effectivity, and robustness. Leveraging Infineon’s proprietary Sealed Twin Membrane (SDM) expertise, each microphones obtain a excessive degree of robustness in opposition to water and dirt (IP57), making them appropriate to be used in demanding environments.
The IM72D128V is distinguished by its top-tier Sign-to-Noise Ratio (SNR) of 71.5 dB(A), making it notably suited to functions requiring exact low-noise audio pick-up. It operates at ultra-low energy consumption, with 430 µA in high-performance mode and
160 µA in low-power mode, which makes it very best for energy-efficient, battery-powered gadgets corresponding to high-end headphones. With a footprint of 4 x 3 x 1.2 mm³, it’s nonetheless sufficiently small to suit most area constraint shopper gadgets.
The IM69D129F is tailor-made for compact design, with a footprint of three.5 x 2.65 x 0.98 mm³, which makes it very best for space-constrained gadgets. It achieves dependable audio efficiency with an SNR of 69 dB(A) and options low energy consumption, working at 450 µA in high-performance mode and 170 µA in low-power mode, contributing to prolonged battery life in transportable gadgets making certain prolonged battery life. Its small dimension makes it notably suited to multi-microphone designs in compact programs. The gadgets can be utilized in Energetic Noise Cancellation (ANC) headphones and earbuds, in addition to high-quality audio capturing in laptops, tablets, convention programs, and cameras.
The IM72D128V and IM69D129F are a part of Infineon’s XENSIV MEMS microphone household, providing distinctive audio high quality, low energy consumption, and excessive sturdiness. In addition they assist Voice Person Interface (VUI) functions in good audio system, automotive infotainment, IoT gadgets, and residential and industrial automation. Moreover, each microphones can be utilized in industrial or residence monitoring functions that require audio sample detection, corresponding to industrial monitoring and residential safety programs.
As well as, the IM72D128V and IM69D129F are outfitted with a low-noise preamplifier and a sigma-delta ADC, offering digital PDM output for seamless integration into fashionable audio programs. Their shared options embrace an 11 Hz flat frequency response for exact sound replica and a ±1 dB sensitivity tolerance, making them very best for multi-microphone arrays. Whether or not used for far-field audio pick-up or transportable gadgets, these microphones allow high-quality audio capturing in difficult environments whereas enhancing vitality effectivity and reliability. Each microphones adjust to IEC (60747, 60749) and JEDEC (47/20/22) requirements, making certain reliability and robustness for shopper and industrial functions.
