Hello All About Circuits,

I am looking to power a frequency to voltage circuit using a AD650.

The power connections are new to me, I know how to power a -15 gnd +15 but it only has a +5 connection. Where do I link the -5 on my bench power supply?

I'm guessing gnd between -15 +15 or -15? I didn't want to just chance it as the ic is quite expensive and I only have one.

You link the negative and positive centre terminals together to make Chip ground, then set the psu to +15/-15 and put the 5v supply negative to the Chip ground and the +5v to the chip.

Ok so, the 5v supply negative links with the ground between the -15 +15. could I link them on a gnd rail on a breadboard?
