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 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.
