Jun 30, 2023 /SemiMedia/ -- Infineon Technologies AG has recently expanded its automotive microphone portfolio with the launch of the XENSIV™ MEMS microphone IM68A130A. The microphone builds on Infineon's first automotive-grade digital MEMS microphone, the IM67D130A, and features a flat frequency response below 10Hz.
The IM68A130A microphone features a flat frequency response, a stable phase response, and a very low frequency roll-off (LFRO = 10Hz). The high signal-to-noise ratio (SNR = 68dB(A)) and great acoustic overload point (AOP = 130 dBSPL) provide excellent speech performance, making it a perfect product for general-purpose microphones in any audio system. It can also be used for beamforming and ANC, where microphones are strategically placed in the cabin or at exterior locations to detect sounds in the cabin. An inverted sound wave is then generated through the audio speakers to reduce the sound level in the cabin.
Infineon’s new microphone is qualified according to the AEC-Q103-003 standard, which meets the requirements of the automotive industry. This helps to reduce the effort and risk of failure in module and system qualification. The product will be available for at least the typical lifecycle of a vehicle, enabling savings in design-in effort and the development of platform solutions. In addition, its extended operating temperature range of up to +105°C allows for flexible use in various application environments inside and outside the vehicle.
The XENSIV MEMS microphone IM68A130A can be ordered now. For more information, please visit www.infineon.com/mems-microphones-for-automotive/im68a130a/
