MAX44264EWT+T Datasheet MAX44264EWT+T | P1-P3

General Description

The MAX44264 is an ultra-small (6-bump WLP) op amp

that draws only 750nA of supply current. It operates

from a single +1.8V to +5.5V supply and features

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 out-

put stage of the MAX44264 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 sup-

ply. The IC is unity-gain stable and available in a

space-saving 0.9mm x 1.3mm, 6-bump WLP package.
