Datasheet Summary
ICS‐40618
High Dynamic Range Microphone with Differential Output and Low Power
GENERAL DESCRIPTION
The ICS‐40618 is an analog MEMS microphone with very high dynamic range and a low‐power AlwaysOn 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 dB SPL acoustic overload point in high performance mode, tight ±1 dB sensitivity tolerance and enhanced immunity to both radiated and conducted RF interference. ...
