Audio Amplifiers Procurement Notes
Verify component authenticity through authorized distributors. Confirm the specific suffix matches the required package and temperature range. Check for recent Product Change Notices regarding manufacturing updates. Ensure compliance with RoHS3 standards before integration.
Audio Amplifiers Selection Notes
Select this model for space-constrained designs requiring high efficiency. Verify that the system voltage remains within the 2.7V to 5.5V operating range. Ensure the PCB layout supports the small 36-DSBGA footprint. Confirm compatibility with the host controller's digital interface protocols.
Audio Amplifiers Part Context
This component belongs to the Boomer® family of audio amplifiers designed for portable electronics. It replaces older analog-only solutions by integrating digital control capabilities directly onto the chip. The device is part of a broader portfolio aimed at reducing external component counts in mobile devices.
Audio Amplifiers Replacement Considerations
The LM49350RLX/NOPB serves as a verified alternative variant. Both share identical electrical specifications and pinouts. Verify that the specific ordering suffix aligns with the desired packaging configuration.
