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 output 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 supply. The IC is unity-gain stable and available in a space-saving 0.9mm x 1.3mm, 6-bump WLP package.
