If number of steps allow, you can use LED bar=graph driver to convert input
voltage to output steps.  Each ouput can go to diode, followed by resistor to
make a divider where only output pin with "1" contributes to output voltage.  

You will need to amplify the signal and rectify it to convert 50Hz to DC.
