# IM73D122V01XTMA1 (Component) ## Description Ultra-Low Noise Digital MEMS Microphone with PDM Output – High-performance omnidirectional MEMS microphone designed for voice assistants, smart speakers, conferencing systems, industrial voice interfaces, IoT devices, wearables, automotive applications, and embedded audio systems. Part of the Infineon XENSIV™ microphone family, it features a digital PDM output, 73 dB(A) signal-to-noise ratio (SNR), −26 dBFS sensitivity (±1 dB @ 94 dB SPL), and an acoustic overload point (AOP) of 122 dB SPL, delivering excellent speech intelligibility and high dynamic range. Operates from a 1.62 V to 3.6 V supply with 980 µA typical current consumption, supports a 20 Hz to 19 kHz frequency response, and includes multiple operating modes for power optimization. Features a bottom-port acoustic design, IP57 dust and water resistance, and AEC-Q103 qualification (on demand) for demanding environments. Housed in a compact 5-pad LLGA package (4.0 × 3.0 × 1.2 mm) and specified for operation over a −40°C to +85°C temperature range. #Infineon #IM73D122V01XTMA1 #XENSIV #MEMSMicrophone #DigitalMicrophone #PDM #VoiceInterface #SmartSpeaker #IoT #AudioProcessing #AECQ103 #EmbeddedSystems ## Component Details - **Owner:** silicon-yard - **Created:** 7/31/2026 - **Last Updated:** 7/31/2026 - **Visibility:** Public - **License:** https://creativecommons.org/licenses/by/4.0/ - **Manufacturer Name:** Infineon Technologies - **Package or Case Code:** IM72D128V01XTMA1 - **Part Type:** Microphone - **Manufacturer Part Number:** IM73D122V01XTMA1 - **Datasheet URL:** https://www.infineon.com/assets/row/public/documents/24/49/infineon-im73d122-datasheet-en.pdf?fileId=8ac78c8c83cd3081018409cafdfb46db - **Used in:** 10 projects ## Distributor Pricing (qty 1) *Pricing shown for quantity 1.
