Audio Amplifiers Procurement Notes

Verify the manufacturer origin, as National Semiconductor is now part of Texas Instruments. Confirm the specific suffix matches the required packaging format. Ensure the component meets RoHS compliance standards if required by the target application. Cross-reference the datasheet revision to confirm pinout and electrical characteristics align with design specifications.

Audio Amplifiers Selection Notes

Select this component for low-power stereo audio applications requiring a compact surface-mount solution. The 105 mW output is suitable for high-impedance headphones or low-volume portable devices. Consider the thermal performance within the MSOP package when designing the PCB layout for adequate heat dissipation under continuous operation.

Audio Amplifiers Part Context

This component belongs to the LM4811 series of audio amplifiers. It is functionally equivalent to variants such as LM4811MMX/NOPB, differing primarily in reel packaging quantities. The device represents the transition from National Semiconductor to Texas Instruments product lines while maintaining identical core electrical specifications.
