I'm using a PIC microcontroller with an MCP4922 DAC to make a sine wave. Right now I can make a sine wave that goes between 0 and 5V just fine. However, I don't know how to get it to go between -5 and 5 volts, or -2.5 and 2.5 volts. I've never really dealt with negative voltage supplies before. Does anyone have any suggestions on where to start?
Should I just leave the code as is and add some sort of amplifier that will drive it into both the positive and negative voltages? I will be needing an amp anyway, since this is a motor driver, and the current output of the MCP4922 is low. Any recommendations on an amp?
Thanks!
