as attach png file shows,,, it looks OPA power supply range extend to -5.4v -- +5.4v..... and it for no other purpose ????
OPA == AD8605
Thank you for using products from ADI. Is the supply range is what you're asking? If it is, the part can operate at of 0-2.7V or 0-5.5V ranges. What are you trying to achieve in your application? Can you share the whole schematic? It seems like the one you sent is not properly cropped. With that information we can assist you further.Regards,Gauzz
