MAX4484/MAX4486/
MAX4487
Single/Dual/Quad, Low-Cost, Single-Supply
7MHz, Rail-to-Rail Op Amps
General Description
Features
The single MAX4484 is available in the ultra-small 5-pin
SC70, while the dual MAX4486 is packaged in the spacesaving 8-pin SOT23 and μMAXM packages. The quad
MAX4487 is available in the 14-pin SO and TSSOP packages.
Ordering Information
The MAX4484/MAX4486/MAX4487 single/dual/quad lowcost general-purpose op amps operate from a single
+2.7V to +5.5V supply. The op amps are unity-gain stable
with a 7MHz gain-bandwidth product, capable of driving
an external 2kΩ load with rail-to-rail output swing. The
amplifiers are stable with capacitive loads of up to 100pF.
The MAX4484/MAX4486/MAX4487 are specified from
-40°C to +125°C, making them suitable for a variety of
harsh environments.

Detailed Description
Applications Information
Rail-to-Rail Output Stage
Power Supplies and Layout
The MAX4484/MAX4486/MAX4487 can drive a 2kΩ load
and still swing within 50mV of the supply rails. Figure 1
shows the output swing of the MAX4484 configured 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.
www.maximintegrated.com
The MAX4484/MAX4486/MAX4487 operate from a single
+2.7V to +5.5V power supply. Bypass the power supply
with 0.1μF 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 capacitance, minimize trace lengths by
placing external components close to the op amp’s pins.
Use surface-mount components for best results.
