ICS-40618
DESCRIPTION
The ICS‐40618 is an analog MEMS microphone with very high dynamic range and a low‐power Always On mode. The ICS‐ 40618 includes a MEMS microphone element, an impedance converter, and a differential output amplifier. This microphone features
a low‐power mode, which is active when the supply voltage is <2.0 V. In this mode, the ICS‐40618 operates with 55 µA. Other high‐performance specifications include 132 d B SPL acoustic overload point in high performance mode, tight ±1 d B sensitivity tolerance and enhanced immunity to both radiated and conducted RF interference. The ICS‐40618’s electro‐acoustic performance matches the top port ICS‐40619, making this pair of microphones suitable to use together in applications ...
