ICS-40619

Microphones Overview

The ICS-40619 is a high dynamic range MEMS microphone featuring an analog output and differential signal capability. It operates within a voltage range of 1.52 V to 3.63 V, consuming 165 µA to 190 µA of supply current. The device provides a sensitivity of -38 dB ±1 dB and achieves a signal-to-noise ratio of 67 dB. Its frequency response spans from 50 Hz to 20 kHz with an impedance of 5.5 kΩ. Designed for top-port acoustic access, the component functions reliably between -40°C and +85°C in a compact 3.50 mm x 2.65 mm surface-mount package.

Microphones Procurement Notes

Verify component status as the ICS-40619 is officially listed as End-of-Life (EOL). Confirm availability through authorized distributors or secondary market channels, as standard manufacturing supply may be discontinued. Ensure compliance with RoHS3 specifications and check for any Product Change Notifications (PCN) affecting final assembly or material composition prior to procurement.

Microphones Selection Notes

Select this component for applications requiring high signal-to-noise ratio and ultra-low power operation in compact form factors. The analog output interface suits systems utilizing external ADCs. Evaluate the 67 dB SNR against specific voice capture requirements. Consider the top-port orientation for acoustic integration constraints and verify compatibility with the 1.52 V to 3.63 V operating voltage range of the target system.
