How to get ±2.5V AO from NI USB-6009

[DenisGl]

From the manual of NI USB-6009 DAQ, the analog output is 0-5V.

Can I somehow receive -2.5V to 2.5V analog output? May be to fed -2.5V to the GND of the analog Out to shift the voltage ?

 Thank you.

H, Dennis,

I am afraid, you can do it only with an external circuit

as I see, the minimum components are:

-two dual-supply rail-to-rail op-amps

-a 2.500V  voltage reference

-a negative supply of -5V (e.g a small +5V/-5V DC/DC converter, ICL7660)

-five precision resistors

Pros

Yeah...I thought so.

Thank you.
