Stick a resistor in series, about a 20K and a 022mf cap to ground
after that resistor. Start with that and see where that takes you. A
standard r/c time contant, totally passive.  To calculate the length
of the slew it's R (resistance in ohms) x C (capacitance in farads) =
Time (in seconds).  

hope this helps.
