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 MAXM 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 2k 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 -40C to +125C, making them suitable for a variety of harsh environments.

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 0.1F 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 capacitance, minimize trace lengths by placing external components close to the op amp's pins. Use surface-mount components for best results.
