With the launch of the IM72D128V and IM69D129F, two cutting-edge digital PDM microphones built for outstanding audio quality, energy efficiency, and durability, Infineon Technologies has increased the number of XENSIV MEMS microphones in its offering. Both microphones achieve a high degree of resilience against water and dust (IP57) by utilizing Infineon’s exclusive Sealed Dual Membrane (SDM) technology, which qualifies them for usage in challenging settings.
With its superior Signal-to-Noise Ratio (SNR) of 71.5 dB(A), the IM72D128V stands out and is especially well-suited for applications needing accurate low-noise audio pickup.
With 430 µA in high-performance mode and 160 µA in low-power mode, it uses incredibly little power, making it perfect for battery-powered, energy-efficient devices like high-end headphones. Its footprint of 4 x 3 x 1.2 mm³ is still sufficiently tiny to accommodate the majority of consumer products with limited space.
With a footprint of 3.5 x 2.65 x 0.98 mm³, the IM69D129F is designed to be small and perfect for devices with limited space.
With an SNR of 69 dB(A), it provides reliable audio performance. It also uses little power, running at 450 µA in high-performance mode and 170 µA in low-power mode, which helps portable devices’ batteries last longer.
Because of its compact size, it is especially well-suited for designs involving several microphones in small systems. In addition to providing high-quality audio recording in laptops, tablets, conference systems, and cameras, the devices can be utilized in Active Noise Cancellation (ANC) headphones and earbuds.
Infineon’s XENSIV MEMS microphone series, which includes the IM72D128V and IM69D129F, offers remarkable audio quality, low power consumption, and great endurance.
Additionally, they support Voice User Interface (VUI) applications in home and industrial automation, smart speakers, car infotainment, and Internet of Things devices.
Also, both microphones are suitable for use in home security systems and industrial monitoring applications that call for the detection of audio patterns.
A sigma-delta ADC and a low-noise preamplifier are other features of the IM72D128V and IM69D129F, which offer digital PDM output for smooth integration into contemporary audio systems.
They are perfect for multi-microphone arrays since they share characteristics like a ±1 dB sensitivity tolerance and an 11 Hz flat frequency response for accurate sound reproduction.
These microphones improve reliability and energy efficiency while enabling high-quality audio recording in difficult settings, whether they are utilized for portable devices or far-field audio pick-up.
Both microphones are sturdy and dependable for both consumer and commercial applications since they meet JEDEC (47/20/22) and IEC (60747, 60749) standards.
