Detailed Description
Rail-to-Rail Output Stage
The MAX4400–MAX4403 can drive a 2k
load and still
typically swing within 55mV of the supply rails. Figure 1
shows the output voltage swing of the MAX4400 config-
ured with AV = +10V/V.
Driving Capacitive Loads
Driving a capacitive load can cause instability in many op
amps, especially those with low quiescent current. The
MAX4400–MAX4403 are unity-gain stable for a range of
capacitive loads to above 400pF. Figure 2 shows the
response of the MAX4400 with an excessive capacitive
load. Adding a series resistor between the output and the
load capacitor (Figure 3) improves the circuit’s response
by isolating the load capacitance from the op amp’s output.
