The AEC-Q103-003 qualified microphone is suited for intelligent speech recognition and road condition detection applications

To address the need for high performance, low-noise MEMS microphones for automotive applications, Infineon Technologies AG has announced the launch of the XENSIV IM67D130A. It will help simplify the design-in efforts for the industry and reduce the risk of qualification fails.

The microphone has an operating temperature range from -40°C to +105°C that enables various use cases in harsh automotive environments. The high acoustic overload point (AOP) of 130 dB SPL allows the microphone to capture distortion-free audio signals in loud environments. Because of that, it can be placed inside or outside the vehicle.

IM67D130A is ideal for in-cabin applications such as hands-free systems, emergency calls, in-cabin communication and active noise cancellation (ANC). The microphone is also suited for exterior applications such as siren or road condition detection. These features enable the use of sound as a complementary sensor for advanced driver assistance systems and predictive maintenance.

The high signal-to-noise ratio (SNR) of 67 dB combined with low distortion level offers optimum speech quality and intelligence for applications based on speech recognition. Additionally, the microphones have tight sensitivity matching, allowing optimised beamforming algorithms for multi-microphone arrays.

The AEC-Q103-003 standard qualified XENSIV MEMS microphone IM67D130A can be ordered now in a PG-LLGA-5-4 package.
