R112780 Datasheet
A second problem when driving capacitive loads results from the amplifier's output impedance, which looks inductive at high frequencies. This inductance forms an L-C resonant circuit with the capacitive load, which causes peaking in the frequency response and degrades the amplifier's gain margin. The MAX4137/MAX4138 drive capacitive loads up to 10pF without oscillation. However, some peaking (in the frequency domain) or ringing (in the time domain) may occur (Figure 3).

In the Typical Performance Characteristics section of this data sheet, there are curves showing the additional error from nonzero source resistance in the inputs. If there are no large capacitors across the inputs, the amplifier is less sensitive to source resistance and source resistance mis- match. When large capacitors are placed across the in- puts,the input charging currents described above result in larger DC errors, especially with source resistor mis- matches.
