Procurement Notes

Verify component status as this part may be discontinued or subject to product change notices. Confirm availability through authorized distributors and check for valid RoHS compliance documentation. Ensure the specific ordering suffix matches the required packaging format, such as cut tape or reel, before finalizing procurement orders.

Selection Notes

Select this model for applications requiring low-power analog microphone solutions with bottom-port geometry. The 65dB SNR supports clear voice capture in moderate noise environments. Verify that the host system can accommodate the 325 µA supply current and 2.7V operating voltage requirements during the hardware design phase.

Part Context

This component belongs to the Syntiant SiSonic family of silicon microphones. It utilizes MEMS technology to convert acoustic signals into analog electrical outputs. The bottom-port configuration distinguishes it from top-port variants, allowing for different enclosure mounting strategies in compact electronic devices.

Replacement Considerations

Check official Syntiant documentation for qualified replacements. Alternative models within the same series may offer updated specifications or packaging options if this specific part number is no longer in production.
