IM73A135V01XTSA1

IM73A135V01XTSA1 is an IP57 dust and water-resistant analogue XENSIV™ MEMS microphone. It is designed for applications that require a microphone with high SNR, and low distortion, which is also IP57 robust to dust and water. Best-in-class Signal to Noise Ratio of 73dB(A) enables far field and low-volume audio pick-up. The flat frequency response (20Hz low-frequency roll-off) and tight manufacturing tolerance improve the performance of multi-microphone array applications. The high-performance analogue microphone ASIC contains an extremely low noise preamplifier and a high-performance differential output amplifier. Typical applications include active noise cancellation headphones and wireless earbuds, devices with voice user interface, smart speakers, home automation, IoT devices, high-quality audio capturing, conference systems, cameras and camcorders, and industrial or home monitoring with audio pattern detection.
