MAX4400-MAX4403 Single/Dual/Quad, Low-Cost, Single-Supply, Rail-to-Rail Op Amps with Shutdown General Description The MAX4400-MAX4403 low-cost, general-purpose op amps offer rail-to-rail outputs, draw only 320A of quiescent current, and operate from a single +2.5V to +5.5V supply. For additional power conservation, the MAX4401 offers a low-power shutdown mode that reduces supply current to 1A (max) and puts the amplifier's output in a high-impedance state. These devices deliver 1.4mA of output current and are unity-gain stable with a 1MHz gain-bandwidth product driving capacitive loads up to 400pF. The MAX4400-MAX4403 are specified to +125C, making them suitable for use in a variety of harsh environments, such as automotive applications.

Detailed Description Rail-to-Rail Output Stage The MAX4400-MAX4403 can drive a 2k load and still typically swing within 55mV of the supply rails. Figure 1 shows the output voltage swing of the MAX4400 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 MAX4400-MAX4403 are unity-gain stable for a range of capacitive loads to above 400pF. Figure 2 shows the response of the MAX4400 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/Power-Down Waveform Applications Information Power Supplies and Layout Shutdown Mode The MAX4401 features a low-power shutdown mode. When SHDN goes low, the supply current drops to 20pA (typ) and the output enters a high-impedance state. Pull SHDN high to enable the amplifier. Do not leave SHDN unconnected. Figure 4 shows the shutdown waveform. Power-Up The MAX4400-MAX4403 outputs typically settle within 5s after power-up. Figure 5 shows the output voltage on power-up and power-down. www.maximintegrated.com The MAX4400-MAX4403 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.
