"The second problem is with DACs. No matter what combination of Resistors I use,I am not getting a Voltage other than -8.67 volts and that too (too sadly) on both Iout and Iout'. BTW, I am using DAC0800."


If the pins named "Iout" then it schould be a DAC with current output and no voltage output.
Then an opamp was needed to convert I to U.

You should always read the data sheet before you build the pcb !!!
