general description the max4400?ax4403 low-cost, general-purpose op amps offer rail-to-rail outputs, draw only 320? of quies- cent 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 1? (max) and puts the amplifier? output in a high-impedance state. these devices deliver ?.4ma of output current and are unity-gain stable with a 1mhz gain- bandwidth product driving capacitive loads up to 400pf. the max4400?ax4403 are specified to +125?, 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, ?ax , and so packages. the max4403 quad amplifier is packaged in a 14-pin tssop or so. applications single-supply, zero-crossing detectors instruments and terminals portable communications electronic ignition modules infrared receivers sensor signal detection features single +2.5v to +5.5v supply voltage range 320? quiescent current per amplifier 1?
