This microphone features a low-power mode, which is activated when the supply voltage is <2.0 V. In this mode, the ICS-40618 operates with 55 µA.

The ICS-40618 is an analog MEMS microphone with very high SNR and a low-power AlwaysOn mode. The ICS-40618 includes a MEMS microphone element, an impedance converter, and a differential output amplifier.

The ICS-40618’s electro-acoustic performance matches the top port ICS-40619, making this pair of microphones suitable to use together in applications requiring both top and bottom port devices.

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.

The ICS-40618 is available in a small 3.50 mm × 2.65 mm × 0.98 mm bottom port surface-mount package.
