The ICS-40619 is an analog MEMS microphone with very high SNR and a low-power AlwaysOn mode. The ICS-40619 includes a MEMS microphone element, an impedance converter, and a differential output amplifier.
This microphone features a low-power mode, which is activated when the supply voltage is <2.0 V. In this mode, the ICS-40619 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.
The ICS-40619’s electro-acoustic performance matches the bottom port ICS-40618, making this pair of microphones suitable to use together in applications requiring both top and bottom port devices.
The ICS-40619 is available in a small 3.50 mm × 2.65 mm × 0.98 mm top port surface-mount package.
