ICS-40619
DESCRIPTION
The ICS‐40619 is an analog MEMS microphone with very high SNR and a low‐power Always On 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 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‐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.
