The minimum output voltage is within millivolts of
ground for single-supply operation where the load is
referenced to ground (V
voltage range and output voltage swing of a MAX4322
connected as a voltage follower. With a 3V supply and
the load tied to ground, the output swings from 0 to
2.90V. The maximum output voltage swing depends on
the load, but is within 350mV of a 5V supply, even with
the maximum load (500 to ground).

Driving a capacitive load can cause instability in most
high-speed op amps, especially those with low quies-
cent current. The MAX4322/MAX4323/MAX4326/
MAX4327/MAX4329 have a high tolerance for capaci-
tive loads. They are stable with capacitive loads up to
500pF. Figure 4 gives the stable operating region for
capacitive loads. Figures 5 and 6 show the response
with capacitive loads and the results of adding an iso-
lation resistor in series with the output (Figure 7). The
resistor improves the circuit’s phase margin by isolat-
ing the load capacitor from the op amp’s output.
The MAX4322/MAX4323/MAX4326/MAX4327/MAX4329
amplifiers typically settle within 1µs after power-up.
