    ... For convenience, Figure 3 shows R1 vs. R values of R. DESIGN CONSIDERATIONS FOR CAPACITIVE LOADS As with many other opamps, the LMC6442 is more stable at higher closed loop gains when driving a capacitive load. Figure 4 shows minimum closed loop gain versus load ca- pacitance, to achieve less than 10% overshoot in the output small signal response ...

    ... Phase Margin on output voltage is minimized as long as the output load about 1MΩ or less. L Output Phase Reversal: The LMC6442 is immune against this behavior even when the input voltages exceed the com- mon mode voltage range. FIGURE 4.
