with the input capacitance, can create a parasitic pole
that produces an underdamped signal response.
Reducing the input impedance or placing a small (2pF
to 10pF) capacitor across the feedback resistor
improves the response.
The MAX4322/MAX4323/MAX4326/MAX4327/MAX4329’s
inputs are protected from large differential input volt-
ages by 1k
series resistors and back-to-back triple
diodes across the inputs (Figure 2). For differential input
voltages less than 1.8V the input resistance is typically
500k
. For differential input voltages greater than 1.8V
the input resistance is approximately 2k
, and the input
bias current is determined by the following equation:
Rail-to-Rail Output Stage
The minimum output voltage will be within millivolts of
ground for single-supply operation where the load is
referenced to ground (V
EE
). Figure 3 shows the input
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
0.00V to 2.90V. The maximum output voltage swing
depends on the load, but will be 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.
