The MAX4400MAX4403 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 gainbandwidth product driving capacitive loads up to 400pF. The MAX4400MAX4403 are specified to +125C, 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 and SO packages. The MAX4403 quad amplifier is packaged in a 14-pin TSSOP or SO.
