For additional power conservation, the MAX4401 offers a low-power shutdown mode that reduces supply current to 1µA (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 gainbandwidth product driving capacitive loads up to 400pF. The MAX4400–MAX4403 are specified to +125°C, making them suitable for use in a variety of harsh environments, such as automotive applications. The MAX4400 single amplifier is available in ultra-small 5-pin SC70 and space-saving 5-pin SOT23 packages. The single MAX4401 includes the shutdown feature and is available in a 6-pin SC70. The MAX4402 is a dual amplifier available in 8-pin SOT23, µMAX®, and SO packages. The MAX4403 quad amplifier is packaged in a 14-pin TSSOP or SO.

Detailed Description Rail-to-Rail Output Stage The MAX4400–MAX4403 can drive a 2kΩ 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. 100µs/div Figure 1.

Power-Up/Power-Down Waveform Figure 4. Shutdown Waveform Applications Information 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 5µs after power-up. Figure 5 shows the output voltage on power-up and power-down. 8 Power Supplies and Layout The MAX4400–MAX4403 operate from a single +2.5V to +5.5V power supply. Bypass the power supply with a 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.
