1.3mm x 1.3mm, Low-Power

Dual Comparator with Reference

General Description

The MAX44268 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 also features a 1.236V ±1% reference

and a 0.7µA typical supply current per comparator. It has

a rail-to-rail input structure and a unique output stage that

limits supply current surges while switching. This design

also minimizes overall power consumption under dynam-

ic 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.
