USB 6009/6008 analog output

[shjukheter]

I have a circuit which I want to acquire the data from it to labview. Also, the circuit need 5V DC to drive. My doubt is about Can I drive this circuit from USB 6008/6009 i.e. can analog output ports AO0,AO1 produce 5V DC.

I know that they only produce 0-5v signals. I am confused here about DC voltage?

We can't answer that since we don't know what circuit you're trying to drive.  The MANUAL says the analog outputs can only drive 5mA so unless your circuit is very low power you probably don't want to use them to power it.

You could use the analog output (AO1, AO0) to energize a relay which in turn can provide 5V with the required current for the circuit you wish to drive.

Terminal 31 provides a +5V output rated at 200mA. I've used this to drive a circuit with 4 low-power relays without any issues.

 If your circuit requires more current, then you will need an external supply.
