... As the value of the CSLOPE capacitor is increased the slope of the rise and fall time will change correspondingly along with some delay to output. Special control circuitry maintains symmetrical rise and fall times, preserving the LX1991’s ability to provide accurate output current response to very narrow input pulses on the DIG_DIM pin. ...
