MAX4484AUK+T - Maxim Integrated

General Description

The MAX4484/MAX4486/MAX4487 single/dual/quad low-

cost 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.

The single MAX4484 is available in the ultra-small 5-pin

SC70, while the dual MAX4486 is packaged in the space-

saving 8-pin SOT23 and μMAXM packages. The quad

MAX4487 is available in the 14-pin SO and TSSOP pack-

ages.

Typical Operating Characteristics (continued)

Detailed Description

Rail-to-Rail Output Stage

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 capaci-

tive 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 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.
