Datasheet Summary
ICS‐40619
High Dynamic Range Microphone with Differential Output and Low Power
GENERAL DESCRIPTION
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...
