Question about LTC2668

JJbow on Aug 22, 2020

Hi,

I am considering using LTC2668 in our new design. The datasheet says that Pin41 isanalog positive supply and typically should be -15V, but it also must be soldered to PCB. I am confused about this description. Should this pin be grounded or connected to -15V?

Thanks

Where in the datasheet does it say that this is the positive supply? Pin 41 is the paddle and is V-. It must be connected to V- therefore it must be soldered to the PCB, not left floating.
