Analog MEMS Microphone

Analog MEMS Microphone

TDK has introduced the InvenSense ICS-40212 analog microphone, which is a micro electromechanical sensor (MEMS) device with very high dynamic range. It incorporates an impedance converter and an output amplifier. This surface mount MEMS microphone features a low-power AlwaysOn mode that is active when the supply voltage is <2V and operates with 55µA. It features 128dB sound pressure level (SPL) acoustic overload point in high-performance mode, tight ±1dB sensitivity tolerance, and 35Hz to 20kHz extended frequency response.
