Procurement Notes
Verify current product status as the component is scheduled for obsolescence. Confirm availability through authorized distributors or surplus channels. Ensure compatibility with existing PCB footprints and thermal design requirements before procurement. Check for end-of-life notices from Lumissil Microsystems to assess long-term supply chain risks.
Selection Notes
Select this IC for applications requiring a single-channel, high-power audio solution in a dense package. The 48-lead LQFP format supports efficient heat dissipation via the exposed pad. Consider the obsolescence status when designing new products; this part may be suitable for maintenance or replacement roles rather than new designs due to future discontinuation.
Part Context
This device belongs to Lumissil Microsystems' portfolio of audio amplifiers. It represents a specific implementation of Class D technology optimized for mono audio outputs. The manufacturer focuses on connectivity, sensor, and control solutions, positioning this amplifier within their broader audio and video segment offerings for industrial and consumer markets.
Replacement Considerations
No public confirmed substitute part numbers are available in the provided documentation. Due to the scheduled obsolescence, alternative components should be evaluated based on pin compatibility, power rating, and package dimensions. Consult Lumissil Microsystems for recommended next-generation replacements.
