Lac781p Schematic Top -

If you can provide the brand and model of the equipment this part was removed from (e.g., "Kenwood Amplifier Model X-500" or "Ford ECU"), I can locate the service manual which will contain the specific schematic for that board.

Conclusion Following the datasheet recommendations for bypass, decoupling, and grounding is the fastest route to a stable LAC781P-based audio stage. Keep input and output routing separated, use proper bypassing close to pins, and validate gain and bias values on the bench. lac781p schematic top

Insert a P-channel MOSFET and an RC delay on the input side of the LAC781P. This is a common addition in high-end audio schematics to prevent startup thumps. If you can provide the brand and model
