Infineon Technologies AG Sensor technology - MEMS microphones - MEMS microphones for consumer - IM73D122 IM73D122

Description
Ultra-low noise digital XENSIVTM MEMS microphone IM73D122 is designed for applications which require a very high SNR (low self-noise) and a high sensitivity. The flat frequency response (20Hz low-frequency roll-off) and tight manufacturing tolerance improve performance of multi-microphone (array) applications. This microphone is based on Infineon’s new Sealed Dual Membrane MEMS technology which delivers high ingress protection (IP57) at a microphone level. The powerful mix of ultra-high SNR and high sensitivity empowers high quality audio capturing for voice user interface applications in laptops, tablets or conferencing devices. Summary of Features Ultra-low self-noise/ultra-hig h SNR 73dB(A) Very high sensitivity (-26 dBFS) Sealed Dual Membrane (SDM) technology with IP57 ingress protection at microphone level High dynamic range and acoustic overload point (AOP) of 122 dBSPL Very tight part-to-part phase and sensitivity matching (± 1dB) Flat frequency response with a low LFRO (low frequency roll-off) of 20Hz Very low group delay (7µs @ 1kHz) Benefits Powerful far-field and low volume audio pick-up Robust ingress protection (IP57) at a microphone level Enablement of advanced audio features (audio zoom, beamforming) Potential Applications Laptops and tablets Conference systems Smart speakers Home automation and IoT devices Cameras Designers who used this product also designed with BGSA20UGL8 | Antenna tuners CYPD8225-97BZXI | EZ-PD™ CCG8 Dual-Single-Port USB-C PD OPTIGA TPM SLB 9672 FW15 | OPTIGA™ TPM - Trusted Platform Module BGSA20UGL8 | Antenna tuners CYPD8225-97BZXI | EZ-PD™ CCG8 Dual-Single-Port USB-C PD OPTIGA TPM SLB 9672 FW15 | OPTIGA™ TPM - Trusted Platform Module BGSA20UGL8 | Antenna tuners CYPD8225-97BZXI | EZ-PD™ CCG8 Dual-Single-Port USB-C PD OPTIGA TPM SLB 9672 FW15 | OPTIGA™ TPM - Trusted Platform Module
