Procurement Notes

Verify the specific suffix and revision code against the manufacturer's latest datasheet to ensure compatibility with your design requirements. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer before placing orders. Check for any regional distribution restrictions that may apply to this component.

Selection Notes

Select this component when a low-profile, omnidirectional microphone is required for compact designs. Ensure the circuit provides the specified 2 V supply voltage and can handle the 500 µA current draw. Verify that the 2.2 kOhm impedance matches the input requirements of the connected amplifier or ADC stage.

Part Context
