Overview
The WM9094ECS/R is a mono audio amplifier IC manufactured by Cirrus Logic Inc. It supports Class D and Class AB output modes, delivering up to 2W of power into a 4-ohm load with a supply voltage range of 2.7V to 5.5V. The device features thermal protection and depopulation capabilities to enhance system reliability and reduce audible switching noise. It is housed in a compact 20-WCSP package measuring 2.53x2.07mm, suitable for space-constrained mobile multimedia applications.
Feature Summary
- Supports both Class D and Class AB operation modes for flexible efficiency and sound quality optimization
- Integrated thermal protection circuitry prevents damage during high-power operation or overheating conditions
- Depopulation feature minimizes audible popping noises during power-up and power-down sequences
Applications
- Mobile multimedia devices requiring mono audio amplification
- Portable consumer electronics with limited board space
- Battery-powered audio subsystems needing efficient power management
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and specific packaging variants (Reel/Cut Tape) prior to ordering. Check current product lifecycle status as availability may vary by region and date. Ensure ECAD models are compatible with your design tools before integration.
Selection Notes
Select this component when mono audio output is sufficient and space constraints require a WLCSP package. Compare Class D efficiency against Class AB linearity requirements based on application needs. Verify supply voltage compatibility with the 2.7V to 5.5V operating range. Consider thermal performance under maximum load conditions within the specified temperature range.
Part Context
This part belongs to Cirrus Logic's audio amplifier portfolio, designed for mobile and portable applications. It complements other audio codecs and amplifiers in the company's ecosystem, offering integrated solutions for complete audio subsystems in smartphones and tablets.
Replacement Considerations
Check for updated revisions within the WM9094 series. Consult official substitution guides for pin-compatible alternatives if this specific suffix is obsolete. Verify electrical parameters match exactly before replacing in existing designs.
