描述 Description

The IM68A130V01 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.

Each IM68A130V01 microphone is calibrated with an advanced Infineon calibration algorithm, resulting in small sensitivity

tolerances (± 1dB).
