Single/Dual/Quad, Low-Cost, Single-Supply, Rail-to-Rail Op Amps with Shutdown
General Description
The MAX4400MAX4403 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 outputs 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 MAX4400MAX4403 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 a v a i l a b l e in 8-pin SOT23 and SO packages. The MAX4403 quad amplifier comes packaged in a 14-pin TSSOP or SO.

Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
