High performance analog XENSIV™ MEMS microphone The IM68A130 is a high performance, single-ended, analog MEMS microphone designed for applications which 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 analog microphone ASIC contains an extremely low noise preamplifier providing constant current consumption (110µA) over VDD.
