General 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 cur-
rent, low-operating voltage, and rail-to-rail output capa-
bilities 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 com-
pensated and decompensated 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-sav-
ing WLP, SC70, SOT23, MAX, and TSSOP packages.
