I am thinking about a control circuit for CVs in any one of the available AOUT modules.
The concept involves a -10 to 0 V source derived from the DAC and an inverting amplifier. The second op amp stage can do one of three things:
1. Inverting buffer (voltage level = 0 to 10 V)
2. Inverting amplifier (voltage level = 0 to 5 V)
3. Inverting mixer (voltage level = -5 to 5 V)
This would be accomplished by an ON-OFF-ON DPDT toggle switch. Case 1 allows the voltage to pass without any fu
