Has anybody any suggestions of max regulated frequency?
If I replace bottom resistor of feedback chain by digital potentiometer and reduce output capacitor, what "max frequency" very aprox could I send to digital potentiometer, aiming at microstepping motor applications?
LM3485 can work at >1mhz.

  Thanks.
  Mike.
