The MAX4471ESA+ is a dual, rail to rail op-amp in 8 pin NSOIC package. This micropower op-amp operates from a single +1.8V to +5.5V supply and draws only 750nA of supply current. The ultra low supply current, low operating voltage and rail to rail output capabilities make this operational amplifier ideal for use in single lithium ion (Li+) or two-cell NiCd or alkaline battery systems. The amplifier is capable of driving the output voltage to within 4mV of the rail with a 100Kohm load and can sink and source 11mA with a +5V supply. Typical applications include micropower thermostats, electrometer amplifiers, solar powered systems, remote sensor active, badges and pH meters.
