Procurement Notes

Verify the specific suffix G4 indicates lead-free compliance and RoHS adherence before procurement. Confirm the HTQFP or HSSOP package variant matches your PCB footprint requirements. Ensure the design accounts for the specified thermal management needs given the high power output capabilities. Check for any obsolescence notices or recommended new designations from the manufacturer prior to finalizing the bill of materials.

Selection Notes

Select this component when a robust, multi-channel solution is required for automotive environments. It is suitable for designs needing high power density with minimal external components. Consider the 32 dB fixed gain and single-ended input compatibility with existing DSP or source units. Evaluate the thermal performance in the intended enclosure to ensure stable operation at maximum load conditions.
