HI,
The spice model for the ltc2688 has pins that aren't defined in the data sheet. How does the spice model work?
Namely Vdac and NO
Thanks
Matt

Vout should be directly connected to NO for proper operation. If you open the macromodel of the LTC2688 you'll see the proper setup of the model.
The LTC2688 LTspice model only models the behavior of the output buffer. The model is like a non-inverting op amp buffer with NO being the negative input of the op amp and Vdac being the positive input…
Ok makes sense.
Does there need to be feedback resistors or input resistors for gain and input balance like an opamp?
Current plan is to hook up NO to GND and Vdac to a spice voltage source that has the…

Current plan is to hook up NO to GND and Vdac to a spice voltage source that has the same voltage that I want out of the buffer. Is this inline with the expected use of the simulation model?
Thanks

I just found the examples directory with the the LTC2688 circuit and I now see how its expected to be connected.
Thanks Clarence!
