Detailed Description
Rail-to-Rail Output Stage
The MAX4484/MAX4486/MAX4487 can drive a 2k
load and still swing within 50mV of the supply rails.
Figure 1 shows the output swing of the MAX4484 con-
figured with AV = +1V/V.
Driving Capacitive Loads
Driving a capacitive load can cause instability in many
op amps, especially those with low quiescent current.
The MAX4484/MAX4486/MAX4487 are unity-gain stable
for a range of capacitive loads up to 100pF. Figure 2
shows the response of the MAX4484 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.
Applications Information
Power Supplies and Layout
The MAX4484/MAX4486/MAX4487 operates from a sin-
gle +2.7V to +5.5V power supply. Bypass the power
supply with 0.1F capacitor to ground.
Good layout techniques 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. Use surface-mount
components for best results.
