Procurement Notes

Verify the component against official Cirrus Logic documentation to confirm authenticity and revision status. Ensure compatibility with system voltage requirements and package specifications before integration. Check for RoHS compliance and environmental certifications as specified in the datasheet. Confirm availability and lead times directly with authorized distributors or manufacturers.

Selection Notes

Select this component for applications requiring high-fidelity audio processing with integrated power amplification. Consider its low power consumption features for battery-operated devices. Evaluate the need for multiple digital microphone inputs and advanced digital signal processing functions like parametric EQ and dynamic range control when determining suitability for the specific design architecture.

Part Context

The WM8958 belongs to the Wolfson Microelectronics (now Cirrus Logic) family of highly integrated audio CODECs. It is specifically engineered for mobile platforms where space and power efficiency are critical constraints. The device combines analog-to-digital and digital-to-analog conversion with output stage drivers, reducing the bill of materials and board space required for complete audio subsystems in consumer electronics.
