| As I mentioned, the venerable, but now discontinued RC4194 did this, i.e. it provided a bipolar output, the voltage offset from common controlled by a single potentiometer. In the raw form, i.e. without external pass members, it provided only 250 mA over its 42-volt range.  
 I've looked, but haven't seen any sort of monolithic solution. If you run into anything, please let me know. RE |
