Infineon takes lead in MEMS microphone market, launches new technologies for further improved acoustical performance and power consumption

Infineon IM73A135

According to research consultancy Omdia, Infineon Technologies has successfully positioned itself as the market leader for MEMS microphones. Based on MEMS chip unit sales, the market share was reported to have been catapulted to a staggering 43.5 percent. This positions Infineon at #1 with a lead of almost 4 percentage points over second place and more than 37 percentage points over third place. This positive development is due also to Infineon’s long-term experience in MEMS microphone design and high volume manufacturing for delivering an unmatched consumer experience.

Infineon - IM73A135

Now Infineon is launching a next-generation analog MEMS microphone that renders even better results – the XENSIV™ MEMS microphone IM73A135. In microphones, designers often have to accept trade-offs: high signal-to-noise ratio (SNR), a small package, high acoustic overload point, low power consumption, MEMS versus electret condenser microphones (ECM). For this reason, applications that require highest performance microphones may have previously still used ECMs instead of MEMS. The IM73A135 reduces the need to compromise.

A 73 dB SNR and a high acoustic overload point (135 dB SPL) make for a very high dynamic range microphone with a small footprint of 4 × 3 × 1.2 mm. Infineon’s new MEMS microphone also features tight frequency curve matching for the most effective audio signal processing and the industry’s lowest power consumption of 170 μA. The IM73A135 thus allows designers to reach a level of high audio performance restricted to ECMs while at the same time reaping the benefits inherent in MEMS technology.

Infineon’s new MEMS microphone offers excellent characteristics to enhance active noise cancellation in headphones, a market that will grow to approximately 250 million devices by 2025 with a CAGR of 16 percent. Additionally, the low self-noise makes the IM73A135 especially suited for high-quality audio capturing required in conference systems, cameras, or audio recorders. A market that is also expected to increase significantly.

Availability

The XENSIV MEMS microphone IM73A135 will be available for the distribution market in March 2021. The new MEMS microphone technology for wearables will be launched by the “Infineon-inside” partners in the next months.
