The MAX4490/MAX4491/MAX4492 single/dual/quad, low-cost CMOS op amps feature Rail-to-Rail input and output capability from either a single 2.7V to 5.5V supply or dual 1.35V to 2.75V supplies. These amplifiers exhibit a high slew rate of 10V/s and a gain-bandwidth product of 10MHz. They can drive 2k resistive loads to within 55mV of either supply rail and remain unitygain stable with capacitive loads up to 300pF. The MAX4490 is offered in the ultra-small, 5-pin SC70 package, which is 50% smaller than the standard 5-pin SOT23 package. Specifications for all parts are guaranteed over the automotive (-40C to +125C) temperature range.
