Procurement Notes

The WM8727CGED/R is listed as discontinued or end-of-life by the manufacturer. Availability is restricted, and components may only be found through secondary market distributors. Verification of part authenticity and condition is critical due to the obsolete status. Standard packaging quantities historically included reels of 3,000 units. Designers should consider alternative active parts for new production runs.

Selection Notes

This component is suitable for applications requiring high-fidelity stereo audio output with low power consumption. It is appropriate for battery-operated devices due to its single-supply capability and efficient architecture. Engineers should verify compatibility with their system's digital audio interface, specifically I2S protocols. The 8-SOIC package requires adequate PCB space and thermal management considerations within the specified operating temperature range.

Part Context

The WM8727 belongs to Cirrus Logic's WM87xx series of audio codecs and DACs. It is often paired with ADC counterparts like the WM8738 in complete audio solution designs. The 'CGED/R' suffix indicates the specific package type (SOIC), temperature grade, and tape-and-reel packaging format. This part represents a specialized audio conversion solution optimized for consumer electronics.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Due to the discontinued status, engineers must evaluate pin-compatible or functionally similar active components from Cirrus Logic or other manufacturers. Compatibility checks regarding interface protocols, voltage levels, and package dimensions are essential when selecting alternatives.
