Mic balances low power use with high audio quality
The IM69D129F low-power MEMS microphone, part of Infineon’s XENSIV lineup, helps extend battery life in portable devices. In high-performance mode, it consumes only 450 µA at 3.072 MHz, dropping to just 170 µA at 768 kHz in low-power mode.
Designed for space-constrained designs, the IM69D129F provides reliable audio performance with a 69-dB(A) SNR in a compact 3.50×2.65×0.98-mm package. Infineon’s sealed dual-membrane (SDM) technology adds IP57-rated protection again water and dust, making the microphone well-suited for active noise cancellation (ANC) headphones and earbuds, voice-enabled devices, laptops, tablets, conference systems, and cameras.
The IM69D129F microphone integrates a low-noise preamplifier and a sigma-delta ADC, delivering digital pulse density modulation (PDM) output for seamless use in modern audio systems. Its 11-Hz flat frequency response and ±1-dB sensitivity tolerance enable accurate audio capture across multi-microphone arrays.
The IM69D129F is available to order, with customer samples offered on request.
