Procurement Notes

Verify the specific suffix and tape/reel configuration against the manufacturer's latest documentation before ordering. Confirm that the operating voltage range aligns with your system's power rails. Ensure ESD handling procedures are followed during assembly due to the sensitivity of MEMS structures. Check for any recent lifecycle status updates or obsolescence notices from Analog Devices.

Selection Notes

Select this component when ultra-low quiescent current is critical for extending battery life in portable applications. The analog output requires external amplification or ADC stages compatible with the specified impedance. Consider the small form factor if board space is limited. Verify that the required frequency response meets the application's audio bandwidth needs, as detailed specifications may vary by revision.

Part Context

This part belongs to the ADMP803 series of MEMS microphones designed for high-performance audio applications. It represents a silicon-based solution offering consistent performance across temperature ranges. The series is engineered for integration into compact electronic devices where size and power efficiency are primary constraints.

Replacement Considerations

Check Analog Devices' official substitution guide for pin-compatible alternatives. Verify that any substitute maintains the same analog output characteristics and supply voltage requirements. Cross-reference package dimensions to ensure mechanical fit.
