Procurement Notes
Verify the specific suffix and revision level against official Syntiant documentation to ensure compatibility with target designs. Confirm that the analog output characteristics align with the system's input requirements. Check current product status as components may be subject to discontinuation or lifecycle changes without prior notice.
Selection Notes
Select this component when a small form factor and analog interface are required for MEMS microphone applications. Ensure the operating voltage range of 1.5 V to 3.6 V matches the system power rails. Consider the 100 Hz to 10 kHz frequency response limits for intended audio bandwidth requirements.
Part Context
This part belongs to the SiSonic™ series of MEMS microphones manufactured by Syntiant. The series includes various configurations optimized for different size and performance constraints in portable and consumer electronic devices.
Replacement Considerations
Consult official Syntiant documentation for verified substitute part numbers. Do not assume cross-compatibility with other manufacturers' MEMS microphones due to potential differences in electrical characteristics and mechanical dimensions.
