Audio Amplifiers Procurement Notes

Verify the manufacturer designation as National Semiconductor, noting that this entity has undergone corporate restructuring. Confirm the specific suffix 'ITLX' corresponds to the intended tape-and-reel packaging variant rather than bulk or other formats. Ensure the component matches the 36-pin μSMD physical outline and electrical specifications before integration into designs.

Audio Amplifiers Selection Notes

Select this component for stereo audio applications requiring Class-AB performance in a compact surface-mount form factor. Consider the 36-pin density and small footprint when designing PCB layouts. Verify compatibility with standard single-supply voltage levels of 3 V or 5 V for the target system architecture.

Audio Amplifiers Part Context

This part belongs to the National Semiconductor audio amplifier family, specifically designed for portable consumer electronics. The μSMD package allows for high-density board assembly. The product line focuses on delivering stereo sound capabilities within constrained physical spaces typical of mobile devices.

Audio Amplifiers Replacement Considerations

Consult official replacement guides for equivalent stereo audio amplifiers in similar packages. Verify pinout compatibility and electrical parameters before substituting with components from other manufacturers.
