About

XENSIV™ MEMS microphones for unprecedented precision and quality

XENSIV™ MEMS microphones feature ultra-low self-noise (high SNR), extremely low distortions (THD) even at high sound pressure levels (SPL), very tight part-to-part phase and sensitivity matching, a flat frequency response with a low frequency roll-off (LFRO), and an ultra-low group delay. Combined with selectable power modes and their very small package size, Infineon XENSIV™ MEMS microphones are a perfect match for consumer electronics with excellent audio capturing functionalities. 

Infineon’s XENSIV™ MEMS microphones are designed for capturing audio signals with unprecedented precision and quality. The microphones comprise Infineon’s world’s best-selling microphone components.

Due to advanced technical characteristics, high quality standards and robustness at the chip level, Infineon MEMS microphones give hearing to multiple applications beyond the consumer segment, including medical products (e.g., patient monitoring) or industrial (e.g., predictive and preventive maintenance, security).

 

XENSIV™ MEMS microphones shape the industry on the technology level

MEMS microphones use an electrically charged backplate and a membrane to form a capacitive sound transducer. The flexible membrane moves proportional to the amplitude and frequency of incoming sound waves. The resulting change in voltage is measured, processed, and output by an integrated analog or digital ASIC. Infineon products use two main MEMS technologies: single backplate technology (SBP) and sealed dual membrane (SDM).

SBP technology

Single backplate technology (SBP) represents an industry standard for mid-end microphones with its simplicity and robustness. Infineon's SBP technology offers the best performance-to-cost ratio, especially for small package sizes. It combines a high performance with SNR values up to 69 dB with a high robustness with an ingress protection level of IP57 as well as strong protection against compressed air, mechanical shocks and many other environmental stress factors.

SDM technology

Sealed dual membrane (SDM) is Infineon’s revolutionary MEMS microphone technology that utilizes two membranes and a charged stator to create a sealed low-pressure cavity and a differential output signal. The architecture enables ultra-high SNR (up to 75 dBSNR) and very low distortions, and delivers high ingress protection (IP57) at a microphone level. Select SDM technology for best-in-class acoustic performance in medium and larger packages.
