High signal-to-noise ratio and low microphone noise
Current consumption of 520μA, half that of other products with similar performance

Infineon Technologies (hereafter Infineon) has launched a PDM microphone suitable for wearables and IoT devices due to its small size and high performance.

Infineon today announced the addition of a new ultra-low-power digital microphone, the IM69D128S, to its XENSIV™ MEMS microphone product portfolio.

This microphone is designed for applications requiring high signal-to-noise ratio (SNR), low microphone self-noise, long battery life, and high reliability.

A high SNR of 69dB(A) enables crisp, clear audio quality without sacrificing battery life.

Additionally, the current consumption of the IM69D128S, which is based on a digital microphone ASIC, is 520μA, which is only half that of other products with similar performance on the market.

The IM69D128S switches between different power and performance profiles without causing any user-detectable audio anomalies.

The PDM (pulse density modulation) microphone uses Infineon's latest sealed dual-membrane MEMS technology to provide a high waterproof rating (IP57) at the microphone level.

IM69D128S is Its extremely low power consumption makes it ideal for battery-critical hearable applications such as true wireless earbuds, over-ear headsets, and hearing aids, while its small size and high performance make it ideal for space-critical applications such as wearables, smartphones, and IoT devices.

Infineon has been the world's leading supplier of MEMS microphones for three consecutive years.

According to a recent survey by Omdia, Infineon's market share as a microphone MEMS/ASIC die manufacturer grew significantly to 45 percent in 2021.

Infineon's MEMS microphone development strategy encompasses all key technologies for microphone products: MEMS, ASIC, and packaging.

Infineon said that this achievement was based on its long-term experience in MEMS microphone design and mass manufacturing.
