Richard said:
There is one feature that I didn't mention, but which sometimes becomes quite useful, and that's an offset voltage between the positive and negative supply. Is that an easy thing to provide when it's needed? Is possible: 
Above scheme allows to provide an individual offset for each supply. Each supply can independently be shifted by +-25V, but will always stay in the allowed window of 0...+25V or 0...-25V respectively. Kai |

| Sounds s a bit unrealistic | 01/01/70 00:00 | |
| This was Kai-bait, in a sense | 01/01/70 00:00 | |
| Keep it simple | 01/01/70 00:00 | |
| That's what I want to do | 01/01/70 00:00 | |

| Goodness! How would that work? | 01/01/70 00:00 | |

| Thanks, Kai, for presenting this circuit | 01/01/70 00:00 | |
Is possible | 01/01/70 00:00 | |
| Well, I said I'd considered a DAC | 01/01/70 00:00 | |
| isn't there a chip that does this? | 01/01/70 00:00 | |
