Procurement Notes

Verify the specific suffix and revision level against the manufacturer's latest datasheet before procurement. Confirm that the analog output requirements match the host system's input impedance and signal conditioning capabilities. Ensure the zero-height package dimensions are compatible with the intended PCB assembly process and mechanical constraints.

Selection Notes

Select this component when a minimal profile is critical alongside standard analog audio capture needs. Compare the -38 dB sensitivity and 100 Hz lower frequency limit against application requirements. Consider the 1.5 V to 3.6 V operating range for compatibility with low-voltage power domains in portable devices.
