Procurement Notes
Verify the End-of-Life (EOL) status before procurement. The manufacturer has issued discontinuance notifications for this part number. Current availability is restricted, and sourcing may require checking secondary distributors or existing stock. Confirm RoHS compliance details through official documentation.
Selection Notes
Select this component for designs requiring integrated mic preamps and low power ADC functionality. Ensure the system design accommodates the specific supply voltage requirements: 1.65V–3.6V for digital logic and 2.7V–5.5V for analog circuits. Verify that the 10-lead WLCSP package fits the PCB layout constraints.
Part Context
This part belongs to the WM8737 series of audio ADCs from Cirrus Logic. It is designed specifically for mobile and portable audio applications where space and power efficiency are critical. The 'CLGEFL/R' suffix indicates the specific package type (WLCSP) and reel packaging configuration.
Replacement Considerations
Due to the EOL status, direct replacements should be evaluated based on pin compatibility and electrical specifications. Consult Cirrus Logic's current portfolio for modern alternatives such as the WM89xx or CS53xx series, ensuring functional equivalence for stereo ADC and mic preamp requirements.
