General DescriptionThe MAX4493/MAX4494/MAX4495 single/dual/quad
general-purpose operational amplifiers are designed
for use in systems powered with dual supplies from
±2.25V to ±5.5V or with a single supply of +4.5V to
+11V. These op amps provide a unity-gain bandwidth
of 5MHz with only 770µA of quiescent current per
amplifier. The wide input common-mode range extends
from 200mV beyond the negative rail to within 1.5V of
the positive supply rail while the output swings within
10mV (RL= 100kΩ) of either rail.
These amplifiers have excellent (110dB) open-loop
gain with very low THD+N of 0.002% (f = 1kHz). The
single MAX4493 is available in a tiny 5-pin SC70 pack-
age and the dual MAX4494 is available in the space-
saving 8-pin SOT23. The quad MAX4495 is available in
both 14-pin TSSOP and 14-pin SO packages. All prod-
ucts are rated at the automotive temperature range of
-40°C to +125°C.

Applications Information
Rail-to-Rail Output StageThe MAX4493/MAX4494/MAX4495 output stage can
drive up to 1kΩand still swing within 200mV of the rails.
Capacitive-Load StabilityDriving 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 Characteristicsgives 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.

full-power bandwidth as a function of the peak-to-peak
AC output voltage.
Power-Up ConditionsThe MAX4493/MAX4494/MAX4495 typically settle within
3µs after power-up. See Power-Up Time in Typical
Operating Characteristics.
Power Supplies and LayoutThe MAX4493/MAX4494/MAX4495 operate with dual
supplies from ±2.25V to ±5.5V. Bypass both VCCand
VEEwith their own 0.1µF capacitor to ground.
Good layout technique helps optimize performance by
decreasing the amount of stray capacitance at the op
amp’s inputs and outputs. To decrease stray capaci-
tance, minimize trace lengths by placing external com-
ponents close to the op amp’s pins.
