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 320µA 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 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
gain-bandwidth 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.

“#”, or “-” in the package code indicates RoHS status only. Package drawings may show a different suffix character, but the drawing
pertains to the package regardless of RoHS status.
Package thermal resistances were obtained using the method described in JEDEC specification JESD51-7, using a four-layer board.

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.

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.

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
5µs 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
0.1µF 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.
