Relatively high voltage precision DAC amplification

However, you don't need to do this, in the 21st century. In 1970 etc it was the only way hence HP and Tek etc developed all those fancy circuits, but now you can get HV devices.

… that’s a good point. For a low volume (especially a one-off!) design, just buying a premium high V device is likely cheaper than developing & properly testing a cascode arrangement.

Same argument applies to precision resistor arrays, I guess.
