6.3.3 Rail-to-Rail Output

The LMC648x output can swing to within a few hundred millivolts of either supply voltage. Use the specified output swing specifications to calculate an approximate output resistance for different sourcing and sinking conditions. Use the calculated output resistance to estimate the maximum output voltage swing as a function of load.
