The IM66D120A is a high-performance digital MEMS microphone designed specifically for automotive applications, meeting the AEC-Q103 qualification standard. It features a flat frequency response down to 7 Hz, making it suitable for active noise cancellation (ANC) and other audio applications requiring low self-noise and high dynamic range. The microphone has a signal-to-noise ratio (SNR) of 66 dB(A) and offers active total harmonic distortion (THD) compensation, allowing for clear speech even at high sound pressure levels (SPL) of up to 120 dB SPL.
This device is housed in a compact 3.5 x 2.65 x 0.98 mm surface-mount package and is environmentally robust with an IP57 rating, ensuring durability in harsh conditions. It operates over a wide temperature range of -40°C to +105°C, making it versatile for various placements within and outside vehicles. The IM66D120A utilizes a digital PDM output, which simplifies integration into digital audio systems. Its close sensitivity and phase matching characteristics enhance performance in multi-microphone setups and beamforming applications.
XENSIV™ - IM66D120A high performance digital MEMS microphone: best fit for automotive applications in particular Active Noise Cancellation
High-performance digital MEMS microphones qualified according to automotive quality standard AEC-Q103-003. They are suited to all applications inside and outside the car, where the best audio performance in harsh environments and a digital PDM interface is required. They also perfectly support acoustic noise cancellation applications with its flat and stable frequency and phase response and a very low LFRO (Low frequency roll-off) at 7 Hz.
