Procurement Notes
Verify the specific RoHS compliance status through official manufacturer documentation, as indicated in product attributes. Confirm the current lifecycle status, which is listed as NRND (Not Recommended for New Designs), to ensure long-term availability and suitability for new production runs. Cross-reference the datasheet for exact thermal and electrical characteristics before finalizing procurement decisions.
Selection Notes
Select this component when a compact stereo solution is required for low-voltage applications operating between 4.5 V and 5.5 V. The QFN-EP-24 package offers a small footprint suitable for space-constrained designs. Consider the NRND status carefully if designing for long-term manufacturing support. Ensure the application can accommodate the specified 0.2% THD+N requirement for acceptable audio fidelity.
Part Context
This part belongs to the BD54 series of audio ICs from ROHM Semiconductor. It falls under the broader category of Audio Amplifiers within the PMIC and Audio ICs subcategories. The device is specifically engineered for high-efficiency sound reproduction in portable formats, leveraging Class-D topology to minimize power consumption while maintaining stereo output capabilities.
Replacement Considerations
No verified substitute part numbers are available in the provided data. Due to the NRND status, alternative components should be evaluated based on pin compatibility, voltage ranges, and acoustic performance specifications.
