MAX4484/MAX4486/ MAX4487

Single/Dual/Quad, Low-Cost, Single-Supply

7MHz, Rail-to-Rail Op Amps


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.

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.
