Driving Capac itive Loads
The MAX4135/MAX4136 provide maximum AC perfor-
mance with no output load capacitance. This is the
case when they are driving a correctly terminated trans-
mission line (i.e., a back-terminated 75
cable).
However, the MAX4135/MAX4136 are capable of dri-
ving capacitive loads up to 10pF without oscillations,
but with reduced AC performance.
Driving large capacitive loads increases the chance of
oscillations in most amplifier circuits. This is especially
true for circuits with high loop gain, such as voltage fol-
lowers. The amplifier’s output resistance and the load
capacitor combine to add a pole and excess phase to
the loop response. If the frequency of this pole is low
enough and phase margin is degraded sufficiently,
oscillations may occur.
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 MAX4135/MAX4136 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).
