IM68A130V01XTMA1

IM68A130V01XTMA1 is a high-performance analogue XENSIV™ MEMS microphone designed for applications that require a low LFRO (10Hz), a high SNR (low self-noise), and low distortion (high AOP). The high signal-to-noise ratio (SNR) of 68dB(A) enables far-field and low-volume audio pick-up. The flat frequency response and tight manufacturing tolerance improve the performance of Active Noise Cancellation (ANC) and multi-microphone array applications. The high-performance analogue microphone ASIC contains an extremely low noise preamplifier providing constant current consumption (110µA) over VDD. The potential application includes active noise cancellation (ANC) headphones and earphones, smartphones and mobile devices, devices with Voice User Interface (VUI), smart speakers, home automation, IoT devices, high-quality audio capturing, laptops and tablets, conference systems, cameras and camcorders, industrial or home monitoring with audio pattern detection.
