... Total Harmonic Distortion vs. Frequency graph in the Typical Operating Characteristics). Low Distortion • The decompensated devices (MAX4266/MAX4267/ MAX4269/MAX4270) deliver the best distortion per- formance since they have a slightly higher slew rate and provide a higher amount of loop gain for a given closed-loop gain setting. ...

... To ensure a load capacitance that limits peaking to less than 2dB, select a resistance value from Figure 2. For example, if the capacitive load is 100pF, the corre- sponding isolation resistor is 6Ω (MAX4266/MAX4269). Figures 3 and 4 show the peaking that occurs in the fre- quency response with and without an isolation resistor. ...
