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 750nA 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 NiCd 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 4mV of the rail with a 100k load, and can sink and source 11mA with a +5V supply. These amplifiers are available in both fully compensated and decompensated versions. The single AX4470, dual MAX4471, and the quad MAX4472 are nity-gain stable. The single MAX4464 and the dual AX4474 are stable for closed-loop gain configurations of +5V/V. These amplifiers are available in space-saving SC70, SOT23, MAX, and TSSOP packages.
