ICS-40212Analog Microphone with Low Power ModeThe ICS-40212 is an analog MEMS microphone with very high dynamic range and a low-power AlwaysOn mode. The ICS-40212 includes a MEMS microphone element, an impedance converter, and an output amplifier. This microphone features a low-power mode, which is active when the supply voltage is <2.0V. In this mode, the ICS-40212 operates with 55 μA. Other high-performance specifications include 128 dB SPL acoustic overload point in high performance mode, tight ±1 dB sensitivity tolerance. The ICS-40212 is available in a small 3.50 × 2.65 × 0.98 mm bottom port surface-mount package. |
