EVALUATION KIT AVAILABLE MAX4480-MAX4483 Single/Dual/Quad, Low-Cost, Single-Supply, Rail-to-Rail Op Amps with Shutdown General Description The MAX4480-MAX4483 low-cost, general-purpose op amps offer rail-to-rail outputs, draw only 50A of quiescent current, and operate from a single +2.5V to +5.5V supply. For additional power conservation, the MAX4481 offers a low-power shutdown mode that reduces supply current to 0.5A (max) and puts the amplifier's output in a high-impedance state. These devices are unity-gain stable with capacitive loads up to 400pF. The MAX4480- MAX4483 are specified to +125C, making them suitable for use in a variety of harsh environments. The MAX4480 is a single amplifier offered in a tiny 5-pin SC70 package. The MAX4481 is a single amplifier with a low-power shutdown mode that reduces supply current to < 0.5A and comes in a 6-pin SC70 package. The MAX4482 is a dual amplifier and comes in the space-saving 8-pin SOT23 or MAX(R) package. The MAX4483 is a quad amplifier and comes in a 14-pin TSSOP package. All devices are specified for operation across the -40C to +125C automotive temperature range.

Detailed Description Rail-to-Rail Output Stage The MAX4480-MAX4483 can drive a 5k load and still typically swing within 80mV of the supply rails. Figure 1 shows the MAX4480 output voltage swing configured with AV = +10V/V. 1V/div Driving Capacitive Loads Driving a capacitive load can cause instability in many op amps, especially those with low quiescent current. The MAX4480-MAX4483 are unity-gain stable for a range of capacitive loads to above 400pF. Figure 2 shows the MAX4480 response 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 100s/div Figure 1.

Shutdown Waveform Figure 5. Power-Up/Down Waveform Applications Information Power Supplies and Layout Shutdown Mode The MAX4481 features a low-power shutdown mode. When SHDN goes low, the supply current drops to 0.05A (typ) and the output enters a high-impedance state. Pull SHDN high to enable the amplifier. Do not leave SHDN floating. Figure 4 shows the shutdown waveform. Power-Up The MAX4480-MAX4483 outputs typically settle within 50s after power-up. Figure 5 shows the output voltage on power-up and power-down. www.maximintegrated.com The MAX4480-MAX4483 operate from a single +2.5V to +5.5V power supply. Bypass the power supply with a 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.
