MAX4472
Description
The MAX4464/MAX4470/MAX4471/MAX4472/MAX4474 family of micropower op amps operate from a single +1.8V to +5.5V supply and draw only 750n A of supply current. The MAX4470 family feature ground-sensing inputs and Rail-to-Rail ® output. The ultra-low supply current, low-operating voltage, and rail-to-rail output capabilities make these operational amplifiers ideal for use in single lithium ion (Li+), or two-cell Ni Cd or alkaline battery systems. The rail-to-rail output stage of the MAX4464/MAX4470/ MAX4471/MAX4472/MAX4474 amplifiers is capable of driving the output voltage to within 4m V of the rail with a 100kΩ load, and can sink and source 11m A with a +5V supply. These amplifiers are available in both fully pensated and depensated versions. The single MAX4470, dual MAX4471, and the quad MAX4472 are unity-gain stable. The single MAX4464 and the dual MAX4474 are stable for closed-loop gain configurations of ≥ +5V/V. These amplifiers are available in space-saving SC70, SOT23,...
