Audio Amplifiers Procurement Notes

Verify the G4 suffix indicates lead-free construction and RoHS compliance when sourcing. Confirm the DRG4 designation corresponds to the specific SOIC-8 tape and reel packaging variant required for automated assembly processes. Ensure compatibility with existing footprint designs intended for pin-compatible upgrades from legacy LM4880 or LM4881 components.

Audio Amplifiers Selection Notes

Select this component for applications requiring a direct drop-in replacement for LM4880 or LM4881 amplifiers without circuit redesign. It is suitable for battery-powered devices due to its low operating current and single-supply capability. Verify that the 150 mW output rating meets the acoustic requirements of the connected 16-ohm headphones or speakers within the target voltage range.

Audio Amplifiers Part Context

This part belongs to the TPA6111A2 family of stereo audio amplifiers designed for portable consumer electronics.
