Output voltages with high slew rates will require large output load currents. For example if the part is required to
slew at 1000V/μs with a load capacitance of 1nF, the current demanded from the LME49610 is 1A. Therefore,
fast slew rate is incompatible with a capacitive load of this value. Also, if CL is in parallel with the load, the peak
current available to the load decreases as CL increases.
