Procurement Notes

Verify the specific ordering suffix to confirm package type, as variations exist between cut tape and reel formats. Confirm RoHS compliance status through official documentation before integration. Check for active obsolescence notices or product change notifications regarding this discontinued series. Ensure ESD handling protocols are followed during assembly due to the sensitive MEMS structure.

Selection Notes

Select this component when a low-profile, analog-output MEMS microphone is required for voice-centric applications. The 3.35 x 2.50 mm footprint suits space-constrained designs. Verify that the system power supply aligns with the 2.7 V rating and that the 325 µA current consumption fits the power budget. Consider the 65 dB SNR and -38 dB sensitivity for adequate noise performance in typical operating environments.
