Smart home devices

Procurement Notes

Verify the specific suffix DT against official Same Sky documentation to confirm digital output configuration. Ensure the ordering part number matches the required package style and tape/reel specifications. Confirm RoHS compliance status through the manufacturer's latest datasheet before finalizing procurement orders.

Selection Notes

Select this component when a compact digital MEMS microphone with high SNR is required. The 4x3mm footprint suits space-constrained designs. Verify that the system power budget accommodates the 860 uA operating current. Ensure the application environment does not exceed the specified maximum operating temperature of +100°C.

Part Context

This part belongs to the Same Sky CMM series of MEMS microphones. The series offers various sensitivity and package options. The CMM-4030DT variant specifically provides digital output capabilities. It is designed for portable electronic applications requiring reliable audio capture in small form factors.

Replacement Considerations

Consult official Same Sky documentation for verified substitute part numbers. Do not assume cross-compatibility with other manufacturers' MEMS microphones without verifying pinout, electrical parameters, and mechanical dimensions.
