Hi Michael,

In below loop which you have attached is stimulation for OPAMP only, but we are in need for DAC .

Kindly use the below mentioned part number for DAC and give simulation results.

Hi Nishalini,

What type of analysis are you looking for? Attached is a Tina TI file containing both devices. Note that the DAC80004 can only go up to 5.5V output.

And here is the transient result of this circuit. This shows the DAC going full scale (~5V) from 0V, and how fast the OPA responds to this output change.

DAC80004 Transient Sweep.TSC

Thanks,
Erin
