Ultra-Low Power Op Amp in
a Tiny 6-Bump WLP
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.
