Procurement Notes
Verify the specific suffix RV against official Cirrus Logic documentation to confirm packaging and reel specifications. Ensure compatibility with existing board designs regarding pinout and voltage levels. Cross-reference part numbers with authorized distributors to avoid counterfeit components. Check for any recent revisions or obsolescence notices from the manufacturer before procurement.
Selection Notes
Select this component when a balance of audio quality and power efficiency is required for portable electronics. Consider the integrated Class D amplifier if driving speakers directly without external amplification. Verify that the digital interface requirements of the host processor match the codec's supported protocols. Evaluate thermal performance within the enclosure constraints due to the integrated amplifier section.
Part Context
This model belongs to the WM890x series of audio codecs from Cirrus Logic. It is positioned as a cost-effective solution for mid-range portable devices requiring stereo audio capabilities. The LGEFK/RV designation indicates specific packaging and tape-and-reel configuration details defined by the manufacturer.
Replacement Considerations
Direct replacements may include other models from the WM890x family with similar pinouts and feature sets. Verify functional equivalence regarding digital interface support and power supply requirements. Consult Cirrus Logic application notes for recommended pin-compatible alternatives if the exact part is unavailable.
