EVALUATION KIT AVAILABLE
MAX44269
1.3mm x 1.3mm, Low-Power
Dual Comparator
General Description
The MAX44269 is an ultra-small and low-power dual
comparator ideal for battery-powered applications such
as cell phones, notebooks, and portable medical devices
that have extremely aggressive board space and power
constraints. The comparator is available in a miniature
1.3mm x 1.3mm, 9-bump WLP package, making it the
industry’s smallest dual comparator.
The IC can be powered from supply rails as low as 1.8V
and up to 5.5V. It requires just 0.5µA of typical supply
current per comparator. It has a rail-to-rail input struc-
ture and a unique output stage that limits supply current
surges while switching. This design also minimizes over-
all power consumption under dynamic conditions. The
IC has open-drain outputs, making it suitable for mixed
voltage systems. The IC also features internal filtering to
provide high RF immunity. It operates over a -40°C to
+85°C temperature.
