TDK InvenSense ICS-40212 Analog Microphone

TDK InvenSense ICS-40212 Analog Microphone is a Micro Electro Mechanical Sensor (MEMS) microphone with very high dynamic range and a low-power AlwaysOn mode. This microphone incorporates a MEMS microphone element, an impedance converter, and an output amplifier. The ICS-40212 features a low-power mode that is active when the supply voltage is <2V and operates with 55µA.

The ICS-40212 microphone offers 128dB sound pressure level (SPL) acoustic overload point in high-performance mode, tight ±1dB sensitivity tolerance, and 35Hz to 20kHz extended frequency response. This microphone is available in 3.5mm x 2.65mm x 0.98mm dimensions with a bottom port surface-mount package. Typical applications include smartphones, still and video cameras, AlwaysOn listening, wearable devices, and IoT devices.
