Applications Information
Rail-to-Rail Output Stage
The MAX4493/MAX4494/MAX4495 output stage can
drive up to 1k
Ω and still swing within 200mV of the rails.
Capacitive-Load Stability
Driving large capacitive loads can cause instability in
many op amps. The MAX4493/MAX4494/MAX4495 are
stable with capacitive loads up to 300pF. The
Capacitive-Load Stability graph in the
Typical
Operating Characteristics gives the stable operation
region for capacitive versus resistive load. Stability with
higher capacitive loads can be improved by adding an
isolation resistor in series with the op-amp output, as
shown in Figure 1. This resistor improves the circuit’s
phase margin by isolating the load capacitor from the
amplifier’s output. As seen in the
Typical Operating
Characteristics, driving capacitive loads with an isola-
tion resistor exhibits some overshoot, but no oscillation.
