physical interface between Cyclone III & DAC

Hello to all, I am working on a test waveform generator project using the Cyclone III starter kit (3C25N). Once synthesized on the FPGA, the waveform will be sent to a DAC so that it can be vi...

I'm trying to implement a PID controller on my Cyclone III Starter Kit with attached DAC and so I'm looking for a way to output positive or negative DC voltages (-1 to 1 volts, say). Is there any way to modify the DAC on the DAC in order to achieve this output? Also, is there any way to modify the ADC to read in a DC voltage?

Thanks!
