Single/Dual/Quad, +1.8V/750nA, SC70,
Rail-to-Rail Op Amps
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
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 alka-
line 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
100kΩ 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 SC70, SOT23, µMAX, and TSSOP packages.
