Procurement Notes

Verify the specific suffix 'RG4' against the manufacturer's current datasheet to confirm pinout and packaging details. Check for end-of-life status or obsolescence notices on official distributor channels. Ensure the 56-HTSSOP footprint matches your PCB design constraints. Confirm RoHS compliance documentation is available for regulatory requirements in your target market.

Selection Notes

Select this component when a compact, high-power stereo solution is required for 6-ohm loads. It is suitable for designs needing digital audio inputs without external DACs. Consider the thermal performance of the 56-pin package for your enclosure design. Evaluate if the 30W per channel output meets the speaker sensitivity and impedance specifications of the target application.
