The MAX4480–MAX4483 can drive a 5kΩ load and still
typically swing within 80mV of the supply rails. Figure 1
shows the MAX4480 output voltage swing configured
with A
Driving a capacitive load can cause instability in many
op amps, especially those with low quiescent current.
The MAX4480–MAX4483 are unity-gain stable for a
range of capacitive loads to above 400pF. Figure 2
shows the MAX4480 response with an excessive
capacitive load. Adding a series resistor between the
output and the load capacitor (Figure 3) improves the
